Heltec V3 - $20 - $30 (as of 2026-06-08)
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 SMAan external antenna.LoRa antenna that connects via an on-board U.FL/IPEX (IPEX1.0) connector.
- MCU: ESP32-S3
- LoRa chip: SX1262
- Display: 0.96" OLED
- Antenna: External LoRa antenna via on-board U.FL/IPEX (IPEX1.0) connector (many resellers add a U.FL-to-SMA pigtail; the bare board is U.FL/IPEX)
- USB: USB-C
- Battery: JST connector for LiPo (not included)

Heltec Wireless Paper - ~$1516 -from Heltec direct, up to ~$25 via resellers (as of 2026-06-08)
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 (

- Use case: Ultra-low-power fixed node or infrequently checked carry device
Heltec Capsule Sensor V3 - ~$726+ (as of 2026-06-08)
TheAn cheapest supported device. Ultra-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 telemetry/sensor node or(23 g, IP65). Note this is a LoRa/LoRaWAN sensor device, not a general-purpose chat node - confirm it runs the Meshtastic/MeshCore messaging firmware you intend before buying, so it isn't mistaken for buildersa comfortablebeginner withmessaging DIYdevice. work.It is fully integrated: a built-in LoRa antenna, a built-in 250 mAh rechargeable battery, and a magnetic charging port. Sensors attach via a solderless BTB (board-to-board) connector - no soldering of antenna or battery is required.
