PCB Dock Design & C Firmware for Lichee Pi Zero 2nd (4G, GPS, RS485, Camera)
Budget: $250 – $750 USD
I am looking for an experienced Embedded Systems Engineer to design a Dock and develop C firmware for a tracking and monitoring system based on Lichee Pi Zero Second Generation (https://licheepizero.us/)
1. Design PCB Dock:
+ Mini PCIe slot to support Quectel EC25 4G LTE module (USB-based interface over PCIe form factor) - https://www.proe.vn/ec25-mini-pcie-4g-iot-module
+ RS485: UART to RS485 circuit
+ Power supply (peak 3A)
2. Firmware
+ Camera: Capture.
+ GPS: Read data from EC25 module.
+ RS485: send/receive.
Note:
1. Please start your bid by telling me which CPU the Lichee Pi Zero Second Generation uses? This helps me ignore auto-bids
2. Please provide a realistic bid. I will ignore bids that are excessively high or suspiciously low, as they indicate a lack of understanding of the project's technical requirements
