# Heltec Mesh Node T096

## Overview

The **Heltec Mesh Node T096** (Heltec's nRF52 part naming follows the HT-n5262 / HT-n5262M family) combines an nRF52840 MCU with an SX1262 radio and an *integrated power amplifier*. Heltec rates its maximum TX power at **28±1 dBm** via that PA — well above the SX1262's bare native +22 dBm — which it pairs with on-board GPS and an ultra-low sleep current, making it purpose-built for solar and remote deployments. *(TX-power figures for Heltec PA boards are contested across third-party sources; the 28±1 dBm here reflects Heltec's own current spec — verify against [heltec.org](https://heltec.org/project/t096/) before relying on it.)*

## T096 vs. Heltec V4

<table id="bkmrk-featuret096v4-tx-pow"><thead><tr><th>Feature</th><th>T096</th><th>V4</th></tr></thead><tbody><tr><td>TX Power</td><td>28±1 dBm (Heltec, via PA)</td><td>~22 dBm stock (contested; some sources cite up to ~27-28 dBm on PA variants — verify against heltec.org)</td></tr><tr><td>Price</td><td>~$30 (as of 2026-06-08)</td><td>~$17 - 20 (as of 2026-06-08)</td></tr><tr><td>GPS</td><td>Yes (UC6580, L1+L5)</td><td>No</td></tr><tr><td>Wi-Fi</td><td>No</td><td>Yes</td></tr><tr><td>Sleep Current</td><td>12 µA</td><td>Higher</td></tr><tr><td>Best Role</td><td>Solar / remote / field</td><td>Indoor / USB-powered nodes</td></tr></tbody></table>

RF output is **not** identical between the two: the T096 reaches 28±1 dBm via its integrated PA, whereas the Heltec V4's stock output is around 22 dBm (higher on some PA variants — the exact figure is contested, so verify against heltec.org). Beyond raw output, the T096's 12 µA sleep current and built-in GPS make it far more suitable for long-term solar-powered deployments, where the V4's Wi-Fi integration goes unused.

## Target Use Cases

- Solar-powered relay nodes
- Remote repeaters (mountain tops, rural infrastructure)
- Portable field kits requiring GPS without an external module

# Ikoka Stick

## Overview

The **Ikoka Stick** is a community DIY design (by **ndoo**) for an ultra-compact stick-format LoRa node built on the **Seeed Studio XIAO nRF52840** paired with an **EBYTE E22-900M**-series LoRa module. It is a hobbyist build rather than a productized multi-MCU node. The compact stick form factor is suited to use as a pocket companion; higher-power builds (see below) require a larger enclosure and should not be confused with the pocketable stick.

## Variants &amp; Power Options

The base E22-900M module (SX1262) outputs up to **+22 dBm**. Higher-power "variants" are separate enclosure-based builds that use a higher-power EBYTE E22 module (e.g. E22-900M30S at 30 dBm) or add an external power-amplifier stage downstream of the module — these are not the compact pocket stick.

<table id="bkmrk-varianttx-powertypic"><thead><tr><th>Variant</th><th>TX Power</th><th>Typical Use</th></tr></thead><tbody><tr><td>Standard (compact stick)</td><td>22 dBm (~158 mW)</td><td>Personal carry / compact node</td></tr><tr><td>1 W (box build)</td><td>30 dBm</td><td>Infrastructure repeater</td></tr></tbody></table>

**FCC caveat:** The 1 W variant sits at the FCC Part 15.247 conducted limit of 30 dBm (1 W) and is only legal under Part 15 with an antenna of ≤6 dBi (higher-gain antennas require a dB-for-dB conducted-power reduction). A 2 W / 33 dBm build (using EBYTE's large E22-900M33S UART module) **exceeds the FCC Part 15 conducted limit and is not legal for unlicensed US use** — high-power tower use of such a variant generally requires an amateur Part 97 license (no encryption, station identification). Confirm conducted power plus antenna gain against 47 CFR 15.247 before deploying under Part 15. Note also that a 33 dBm module is a large, high-current part (drawing on the order of 1-2 A peak with significant heat dissipation needs) and cannot fit a pocketable stick form factor.

## Key Specifications

- **MCU:** Seeed Studio XIAO nRF52840
- **Radio:** EBYTE E22-900M series (built on the SX1262, rated up to +22 dBm). The 1 W build uses a higher-power E22 module (e.g. E22-900M30S) or an external PA stage added after the base module.
- **Form factor:** Compact stick (the standard 22 dBm build). Higher-power builds require a larger enclosure and heatsinking and are not pocketable.

## Community Deployments

The Ikoka Stick is the basis of [CascadiaMesh](https://wiki.meshamerica.com/books/north-american-networks/page/cascadiamesh)'s *"1 Watt Ikoka Box"* build - one of the most replicated community deployment designs, used for high-density urban and suburban coverage nodes. As an enclosure-based 1 W build, it is distinct from the pocketable standard stick.

## RF Filtering

In electrically noisy environments (near industrial equipment, dense urban RF, tower-share sites), a LoRa cavity filter can suppress out-of-band interference and protect the receiver, improving effective range in difficult RF environments. The Baymesh (Nullrouten) cavity filter is one option; verify the exact SKU, center frequency (US-band LoRa filters are tuned near 906-915 MHz, not a single "910 MHz" point), and current price before purchasing.

## Target Use Cases

- High-power infrastructure repeaters (enclosure-based 1 W box build, not the pocket stick)
- Tower mount and rooftop deployments
- Community mesh backbone nodes

# Harbor Breeze Solar Node (~$10 enclosure, ~$65 total build)

## Overview

The **Harbor Breeze Solar Node** converts a $10 - 15 Harbor Breeze 60-lumen solar LED floodlight (Lowe's item #SL1832) into a weatherproof, solar-powered mesh node. The floodlight already includes a small solar panel (rated ~0.6 W per the Lowe's listing; a rough estimate of ~90 mA at 5 V), an 18650 cell (the listing includes a 3.7 V ~1500 mAh 18650), a charge circuit, and a weatherproof enclosure - the hard parts are done for you. (Prices and specs as of 2026-06-08.)

Total cost including radio: approximately **$60 - 70** (as of 2026-06-08; the total tracks the volatile RAK4631 street price). Enclosure + solar hardware alone: $10 - 15.

## Bill of Materials

*All prices are commodity/street prices as of 2026-06-08 and will vary; recompute the total if the RAK4631 price changes.*

## Assembly Overview

1. Remove the back cover of the floodlight housing.
2. Remove the LED assembly and cut existing wires near the board.
3. Drill a 1/4″ hole through the housing for the SMA bulkhead connector.
4. Install the RAK WisBlock base board and core module inside the housing.
5. Wire the battery: red = positive (+).
6. Wire the solar panel to the RAK19007 solar charge input header - **verify the exact header label and polarity against the RAK19007 datasheet before connecting**.
7. Weatherproof all cable entry points and the SMA hole with silicone sealant.
8. Reinstall the back cover.

## Critical Warnings

- **Keep the solar input within the RAK19007's rated charge-input limit.** Confirm the exact maximum solar/charge input voltage against the current RAK19007 datasheet before connecting; as a conservative ceiling, do not feed more than ~6 V into the solar input. The Harbor Breeze panel is rated ~0.6 W trickle charge. Do not substitute a higher-voltage panel.
- Verify solar wire polarity *before* connecting to the charge-input header. Reverse polarity will damage the charge circuit.
- This panel provides trickle charge only - not suitable for high-duty-cycle backbone repeaters. Nodes that transmit frequently will discharge the battery faster than the panel can recharge it.

## Best For

- Fence lines and yard boundary sensors
- Low-traffic area coverage (parking lots, fields, trails)
- Budget-conscious deployments where AC power is unavailable

*Not recommended for high-traffic backbone repeaters or nodes that need continuous uptime.*

# Best Portable Nodes: Ranked

## Overview

This ranked guide is based on community testing and field deployments.
