Ive had the thermometer on charge for two days now and it still hasnt cracked 87%. Trouble is, they've probably used a cheapo regulator which will thow away too much of the voltage - so it might work when the battery is fully charged but then will stop after a bit. The M.2 module is meant to be inserted into the T-FPGA shield with the following specifications: LILYGO provides some samples for the ESP32-S3 (Arduino) and the Gowin FPGA (Verilog) to blink the FPGAs LED from the ESP32-S3 over I2C or SPI, and theres also a simple Verilog sample to blink the LED directly from the FPGA. Thats why I share my teardowns here as lucid articles! It seems, from what Googling Ive done, that some ESP32 boards come with voltage dividers on board, which are linked to one of the ADC pins. Thats half the actually battery voltage, so to get the latter we need to multiply by 2. However, theres hardly any option available for on/off control of other 5V and 3.3V power supply channels. I would much appreciate help with the following: The waveshare plastic cover only has one hole for micro USB jack. not match PayPal. To work out where we are in this range, we have to introduce the minimum voltage into the equation. 2x Mini Solar Panel (5/6V 1.2W) 3.
