Schematic done for v0.1 of the sensor node! This is the most simplest design possible, with the barebones minimum. An ESP32 breakout, with headers to each side just in case, a reset switch, 6 LEDs, temperature sensor, speaker, and power boost board. All components are through hole at this moment in time. Pretty smooth sailing on this. Next step is to route the circuit board.
Basic code for the node to test input output functionality works. Two LEDs had to change pins as they were input only. PWM on ESP32 for LEDs is different than with the Arduino boards, that was interesting to learn about. Temperature sensor works, and analog input is 12 bit, so from 0 to 4095. Schematic is started. Next step is to complete the schematic, then board layout, and get the proper board outline with mounting holes into the design.
