This is a starter project for the reverse engineering of the "Glo Hyper+" board.
What is on the board:
1 - Hardware battery protection chip (3.7v) complete with two mosfets
2 - Chip bq25898 battery charge (1S 3.7v), controlled from the main controller via I2C (there is a datasheet)
3 - 2.5v micro-power stabilizer for the main microcontroller
4 - 6.5v boost converter switched on by the foot of the microcontroller
5 - Two power mosfets (25A, 60V) with individual drivers (powered by 6.5V)
6 - Peripheral voltage stabilizer for 3.3v (LED power supply), powered by 6.5v
7 - Thermal resistance No. 1, hardware connected to the battery chip (overheating protection)
8 - Thermal resistance No. 2, connected to the microcontroller, I recommend for thermocouple compensation)
9 - Thermal resistance No. 3, connected to the microcontroller, higher temperature inclusion
10 - Dual operational amplifier for connecting two thermocouples to the controller
11 - Central microcontroller STM32G031 (Arm® 32-bit up to 64 MHz,) (12-bit, 0.4 μs ADC).
12 - The board has holes for soldering wires: programmer, uart, thermocouples, output mosfets.
13 - A USB TypeC connector is installed on a short flexible cable for charging the battery and a vibration motor
14 - Control button, connected to the input of the microcontroller
15 - 4 white bright indicator LEDs connected to the outputs of the microcontroller, powered by 3.3V
16 - Power current shunt with amplifier for measuring bipolar current, resolution about 120 at 1A
Implemented in the starter project:
blinking LEDs,
polling the button
polls all ADC inputs via DMA (all their values are visible on the monitor in debug mode)
outputs to the uart the values of all ADC inputs in turn.
