LORA Sensor - Low Power

Completed Posted 3 years ago Paid on delivery
Completed Paid on delivery

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 Layout Electronics Microcontroller Electrical Engineering Circuit Design

Project ID: #26595738
