Review: JYM-C220BI Schematic (Dual-Channel 20A AC/DC Power Module)
- Input (VCC_Pin): Connected to the input of the LDO.
- Capacitor: 10µF Electrolytic or Ceramic capacitor placed between Input and GND.
- Output: The LDO outputs a steady 3.3V. This rail powers the ILI9225 VDD pins.
- Capacitor: 1µF to 10µF capacitor placed between Output and GND for stability.
Motor Output (A+/A-)
: Supplies the rectified DC voltage to the motor brushes.
No Power:
Check the MOV (Metal Oxide Varistor) for damage from voltage spikes or the external fuse.
- CS: Often has a weak pull-up resistor (10
