Hey, I'm making an Atmega 320P-AU based board, I'm going to send it to jlc PCB or PCB way, the DRC is ok
Features:
-
RF <- 1 x LoRa Ra01 (Powered with a dedicated regulator due to 700mah max)
-
Ultrasonic 2 x Hc-rs04
-
Light sensor <- 4 x Cny-70
-
Acelerometer <- 1 x MPU6050
-
Screen <- 1 x i2c Oled 1.3
-
Motor <- 1 x L298
-
Servo <- 3 x Servo pinouts (Powered with a dedicated regulator)
-
I used D0 and D1 with jumpers
-
No USB-UART, only FTDI programmable
-
Crystal guard ring(16.000mhz, necessary?)
