Esp 32 integration

Post by Dick_Long »

I bought one Of your grand central station M4 express. the purple one (looks dope asf by the way) but I also have an esp 32 wrover for a different project and like the built in wifi/bt. If like to add a wrover B to my grand central but with as small of a footprint as possible as to not hide the board with a proto board. This being said. There is an spi connection in the center of the grand central. I was wondering if you make/ or could make breakout board that could just plug right into it essentially integrating the wrover to the grand central (or any mega basically) and only taking up a small footprint. Thank you for your time I look forward to hearing back.

The Metro M4 Airlift really is the compromise of WiFi + M4 in a Arduino UNO form factor. Bonus it is also "dope asf" being purple.

There is a AirLift FeatherWing. You could connect via SPI to your Grand Central Express M4.

If you do not need a lot of GPIOs then maybe just a ESP32-S2. It is small, inexpensive, fast and has an antenna option.

If you really want to combine a M4 + WiFi use the FeatherWing Airlift + Feather M4 to keep it small with plenty of flash and GPIOs.

Sorry just seen your response. I actually just bought a qt py pico because it has the 2mb psram where the s3 qt doesn't. Super small should fit nicely. I'll make a small adapter board the same size as it to mount it to the center spi. Should be here Monday. Another quick question though. What's the name of 12 bit parralel capture plug or what kind of camera can connect to it? I haven't found any info on that

The QtPy ESP32 Pico is a good call.

There are TTL Serial JPEG cameras that Adafruit sells. They would connect through a UART. This link is the guide with both camera types on the right sidebar.

I don't think I've come across a 12-bit parallel capture plug.
