Since this board has only 520KB of RAM I will probably not go much further with MicroPython and just break down and use C. ESPHome worked fine for my PIR sensor / MQTT IoT project, that's an option still for C programming.

M5StickC orange and wearable. I have a few of these because they are cheap, come with lots of sensors, a tiny 80x160 LCD, and are nicely enclosed in a little case. Also has a 6-axis gyro/accelerometer, and a microphone. Also it can detect alien lifeforms in a 100 meter radius.

It uses an ESP32-PICO-M4 processor with 520KB of RAM and 4MB of FLASH. It's supposed to be a wearable so it has a battery. This MCU uses more power than an ESP32S3 if that matters to you.

Initially I set up one with a PIR hat and used it to control a light for about a year. Currently it's offline due to household politics. It works really perfectly for this with an MQTT connection to Home Assistant.

It has some magnets in it so you can stick it to things! Cool.

Batteries - it has an RTC button cell and a tiny (95mAH) LiPo. More of a UPS than a power supply.

Looks like taking it apart is a waste of time, things are pretty packed in there. Don't bother. Have lots of other ESP32 things already.

Development environment

So far I have tried ESPHome, CircuitPython and UIFlow on it so far. I have no interest in UIFlow, but I think since it runs on MicroPython you can ignore "flows" and load code.

Since this board has only 520KB of RAM I will probably not go much further with MicroPython and just break down and use C. ESPHome worked fine for my PIR sensor / MQTT IoT project, that's an option still for C programming.

Projects

Motion sensor -- I have had one deployed for months in our bedroom, it switches on a light in the evening. Works via MQTT I used a RADAR sensor that is too good, it can see through drywall and picks up motion everywhere. I am switching to PIR sensors soon.

LED strip controller -- working on this soon, to control RGBW strips over WiFi, or maybe I will press on with the Nordic nRF52840's and Zigbee.
