LORA Sensor - Low Power
$30-250 USD
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
