The Lilygo TTGO LoRa32 is a development board for LoRa applications based on the ESP32-PICO-D4.

It's available in two versions supporting two different frequency ranges and features the following integrated components:

• ESP32-PICO-D4 chip (240MHz dual core, 600 DMIPS, 520KB SRAM, Wi-Fi)
• SSD1306, 128x64 px, 0.96" screen
• SX1278 (433MHz) or SX1276 (868/915/923MHz) LoRa radio frontend
• JST GH 2-pin battery connector
• TF card slot

Some of the ESP32 I/O pins are accessible on the board's pin headers.
