Budget Devices

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.
