Original New DS4432U+ marking 4432 7 Bit Digital to Analog Converter(DAC) IC FOR Bitaxe Max BM1397 Bitaxe Ultra BM1366

Bitaxe Max BM1397:

Goals：
1. Standalone: can mine 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 from Bitmain.
4. Versatile: solo/pool mining, autotune power/heat/efficiency.

Ерекшеліктер:
1. ESP32-S3-WROOM-1 wifi microcontroller on board
2. TI TPS40305 buck regulator steps down the 5V input to power the BM1397
3. Maxim DS4432U+ current DAC digitally adjusts the BM1397 core voltage from 0.04V to 2.4V
4. TI INA260 power meter measures the input voltage and current of the miner
5. Microchip EMC2101 measures the BM1397 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
