OpenMV WiFi Shield

Overview

Preface:
OpenMV WiFi Shield is a great expansion module, but its price of 350 RMB is prohibitive. This replica requires a single unit cost of 30 RMB. The PCB design and appearance are meticulously replicated to closely resemble the official design.
Solution
: The official OpenMV schematic is used to replicate the official
OpenMV schematic

. However, the official schematic is somewhat abstract. The
ATWINC1500
module is expensive if you can't find a cheap alternative. I opted for a Wi-Fi communication board I bought for 25 RMB on Xianyu (a second-hand marketplace). Because of the disassembly, the outer label was washed away with board cleaning fluid.

. Firmware
: OpenMV provides firmware.
Copy the firmware to the TF card
: import network
wlan = network.WINC(mode=network.WINC.MODE_FIRMWARE)
