Regular readers may recall a couple of years ago I wrote about the M5Stack – https://tech.scargill.net/the-m5-stack/ and here we are again with the M5Stack Core 2 – the ESP32 IoT development kit which comes complete with 2 inch touch display.
The new, upgraded Core2 has 8MB or RAM, a 390maH battery and you can easily add a bunch of peripherals.
My Core2 package arrived this morning, very well packed. And doing nothing more than pressing the ON button, it actually DOES something – ideal for ESP32 novices. Some say a picture is worth 1000 words so here goes – this is all internal – I have no SD mounted – this is straight out of the box. There’s a little Chinese in there but hey, these are early days and the images are just the default demo.
I can’t wait to have a go at the Arduino library on Github which also has sample code, and I suggest rather than me copying a load of specs, interested readers check out the Core2 documentation in the Wiki
I also have the M5Stack ATOM Lite ESP32 Development Board – but more on that later when I get some peripherals which should be in the next few weeks.
This is exciting – there’s a microphone insie the Core2 unit. See the “Sound FFT” section above – I just said “hello” and it started reacting. I’m also seeing a charging indicator – shame I’ve no idea what the Chinese bits mean. There is a sound system in there and some kind of motor/vibrator. In short, lots of things to play with before lifting a programming finger.
