LORA Sensor - Low Power

완료 등록 시간: 3년 전 착불
완료 착불

I need to develop a pcb for a low cost, energy efficient lora transmitter.

The pcb should consider the following:

LORA module

SD card module

LIPO battery charging circuit through 3.7V solar panel

2 i2c inputs with RJ11 connector

Relay that supports 220V load or optocoupler with similar characteristics

Low consumption processor that can be easily programmed. I have thought of esp32-s, RAK4600 (with smt32) or pure smt32.

Initially I want to connect a sht35 sensor using i2c

At the end I need the schematic of the PCB in easyEDA and the files that allow me to send the board to produce

PCB 레이아웃 전자 공학 마이크로콘트롤러 전기 공학 회로 설계
