Budget Devices
Budget-tier devices cost under $30 and are the right starting point for most new users. They support both MeshCore and Meshtastic, are widely available, and have extensive community documentation.
Heltec V3 — $20–$30
The Heltec V3 is the most popular beginner device in the community. It runs an ESP32-S3 paired with an SX1262 LoRa radio, includes a small OLED display, and ships with a short SMA external antenna.
- MCU: ESP32-S3
- LoRa chip: SX1262
- Display: 0.96" OLED
- Antenna: External SMA
- USB: USB-C
- Battery: JST connector for LiPo (not included)
Known issue — stock Bluetooth antenna dropouts: The V3 PCB antenna used for Bluetooth causes frequent BLE disconnects between the device and the companion app. Community fix: desolder the PCB antenna and replace with a 31mm wire soldered to the antenna pad. This is a five-minute mod that dramatically improves BLE reliability.
Heltec Wireless Paper — $15–$25
A unique budget option built around a 2.13" e-ink display. The e-ink panel draws essentially no power between refreshes, giving the Wireless Paper exceptional battery life.
- MCU: ESP32-S3
- Display: 2.13" e-ink (296 × 128)
- Deep sleep current: ~20 µA — among the lowest of any supported device
- Use case: Ultra-low-power fixed node or infrequently checked carry device
Heltec Capsule Sensor — $7
The cheapest supported device. Ultra-compact cylindrical form factor. Requires soldering to attach an antenna and battery connections — not suitable for users who want a plug-and-play experience. Best suited as a fixed sensor node or for builders comfortable with DIY work.
