Goals:
1. Standalone: can work directly to your pool over WiFi. No External computer needed.
2. Embedded: low cost, low maintenance, high availability, high reliability, low power.
3. ASIC: based on the very efficient BM1397/ BM1366/ BM1368
4. Versatile: autotune power/heat/efficiency.
Features:
1. ESP32-S3-WROOM-1 wifi microcontroller on board
2. TI TPS40305 buck regulator steps down the 5V input to power the BM1397/ BM1366/ BM1368
3. Maxim DS4432U+ current DAC digitally adjusts the BM1397/ BM1366/ BM1368 core voltage from 0.04V to 2.4V
4. TI INA260 power meter measures the input voltage and current of the MACHINE
5. Microchip EMC2101 measures the BM1397/ BM1366/ BM1368 internal diode temperature. Also PWM controls the fan and monitors tach output.
6. Two sweet RGB status LEDs
7. 0.91″ SSD1306 OLED I2C Display Module
