Review on 📶 Hiletgo Mini ESP32 Mini 32 Module: Advanced WiFi and Bluetooth Connectivity by John Ghattamaraju

This Lyligo/TTGO T7 v1.3Mine also has the date code 20181008 but I had no problem connecting it to the PC via USB. It started with the Blink T7 v1.0 demo and printed its output perfectly at 115200 bps to the Arduino serial monitor. This requires a CH340 driver, maybe some unlucky computer glitch reviewer has a buggy T7 board, or the CH340 driver itself. there's a bug. I am using wch.cn v3.4.2014.8 driver. This module offers many useful features at a price not normally available in other ESP modules: battery connection and charging circuitry, power switch (on battery only). ), external antenna connector, compact form factor. LED on pin 22 following the example from T7 v1.3 on github (untested).
