Dear Sir.
Firstly I want to ask you about your attached file, where is it? Ican't found on this project description.
meanwhile, let me help you modify your board as well as it's firmware if necessary. I have did lot of project since 2012 for various application, from Hobbyst, Robotic, Industrial, IoT, Audio, and Military purpose.
My Hardware development experience including design of advanced circuit design like high speed digital communication, Different Pair, mixed signal, Switching Power Supply, Isolated I/O, BGA Fan out, Cellular, Bluetooth, and WiFi.
My Firmware development experience including various microcontroller like AVR, STM32, NXP, MSP, Arduino, NRF, ESP. I also familiar with lot if communication peripheral used in microcontroller like UART,SPI,I2C, ADC, DAC, DMA, and many more.
Let me know your response about my proposal.
just message me over chat. let's get started.
