I have had those boards (V1.6) for over a decade, had fun plans for them, but never got around to doing anything with them !
This document will always be a work in progress, even after i finish whatever project I will be making, anything new that I find about this board or similar boards will end up here
The TTGO T9 Audio RGB_LED WM8978 is an
- ESP32 : ESP32-WROVER 802.11 b/g/n + Bluetooth 4.1 LE module with 4MB Flash, 4MB PSRAM
- audio chip (WM8978 stereo CODEC)
- SD card slot and 18 RGB LEDs.
- Gyroscope++: InvenSense MPU-9250 : 9-axis motion-tracking sensor IMU 9-DOF MPU-9250 9-Axis Attitude + Gyroscope + Accelerator + Magnetometer Sensor Module
- Battery: The circuitry to charge and use a battery in UPS mode !
- built-in microphone
- 3.5mm audio jack
Now that I might have some free time soon, I decided to compile the resources here for my reference, and to see what fun project they might be good for !
