Notes
Heltec V3
ESP32-S3
Most popular beginner choice; stock BT antenna issue (see Budget Devices page)
Heltec V4
ESP32-S3
~22 dBm (confirm against Heltec's current spec - some sources cite 28 dBm via an integrated PA, others ~22 dBm); solar charging interface
Heltec T114
nRF52840
Lower power than ESP32; DFU (double-tap) flashing
Heltec Wireless Paper
ESP32-S3
E-ink display (250×122); ~20 µA deep sleep (figure quoted for Heltec's V4; verify against the Wireless Paper datasheet)
LilyGo T-Beam
ESP32
GPS built-in; 18650 holder
LilyGo T-Deck
ESP32-S3
QWERTY + touchscreen standalone node
LilyGo T-Echo
nRF52840
E-ink + GPS + NFC; ~850 mAh internal battery (~5 - 7 day runtime)
RAK4631 (WisBlock)
nRF52840
Modular platform; DFU flashing
Wio Tracker L1
nRF52840
OLED + GPS; bare board
Wio Tracker L1 Lite
nRF52840
Most affordable Wio option; includes L76K GPS (drops the OLED screen vs the standard L1, not GPS)
Wio Tracker L1 Pro
nRF52840
Rugged enclosed, GPS, built-in battery
SenseCAP T1000-E
nRF52840
Credit-card size, IP65, GPS; LR1110 radio
Station G2
ESP32-S3
High-power base station (SX1262 + 35 dBm PA + LNA, ~36.5 dBm US915 output). Note: 36.5 dBm conducted exceeds the US FCC Part 15.247 30 dBm conducted limit; full-power US use requires amateur Part 97. See Base Station Nodes.
Firmware Variants
When flashing MeshCore you choose a firmware variant:
Companion: Personal device that pairs with a phone app over BLE or USB.
Repeater: Autonomous mesh relay node; no user interaction needed after setup.
Room Server: Acts as a message store-and-forward hub for a channel.
nRF52 vs ESP32 Considerations
nRF52840-based devices (T-Echo, T114, RAK4631, Wio series, SenseCAP T1000-E) draw significantly less power than ESP32 equivalents, making them better suited for battery-critical deployments. The trade-off is a different flashing workflow: nRF52 devices typically use USB DFU with a double-tap reset (the UF2/USB DFU bootloader) rather than the BOOT-button (esptool) bootloader used on ESP32 boards. See the Meshtastic nRF52 flashing docs.
