Heltec WiFi LoRa 32 V3 (ESP32 + LoRa + OLED 0.96")

Small, rich in feature development board from Heltec. It is based on ESP32 (so You have WiFi and Bluetooth connectivity on board) and Semtech SX1276 radio chip. This is great device for prototyping LoRa based products.

This module is improved over WiFi LoRa 32 v2. Main differences:

• micro USB connector replaced with USB C
• ESP32-D0 replaced by ESP32-S3
• SX1276 was replaced and now board uses SX1262
• in deep sleep mode power consumption is below 10 µA (was 800 µA)

Remember to connect antenna (included) to LoRa radio before powering board. Powering board w/o antenna connected may result in LoRa radio malfunction.
