Dual ESP-32-PCB with 6-IRQ, 4 stepper motors, 1-ADS1256, USB_SD, nRF24
PCB BRD with
1. Size 190mm by 1mm or less with 1 side 140mm min and 140 by 10mm not used (Blanc), this strip is used to be plug in the sockets for holding.

Design OPAL PCB using 2 ESP32 processors
1 ESP32-Master
1. nRF24 –2pins(SPI)
2. SPI-3pins
3. SD_USB-0pins(con to Data_TX duplicate)
4. ADC1256-24bit-2pins(SPI)
5. 4-IRQ-Fast(1000HZ)-Opto-4pin
6. 3 UART-TX/RX -6pins
7. 4 single lines on Opto -4 pins
8. Total =2+3+2+4+6+4=21pins
1 ESP32-second
1. //nRF24 –2pins(SPI)-0pins
2. SPI-3pins
3. //SD_USB-2pins-0pins
4. Can be on board A/D // ADC24-2pins(SPI)
5. 4-IRQ-Slow (200HZ)on OPTO-4pin
6. 2 UART-TX/RX -4pins
7. 4 St-Motors =12pins
Total= 3+2+4+4+12=25pins
