Great video Leon, those XIAO devices are amazing and I cant wait to see more of your projects with it (them). Have you made a keyboard with it as you have mentioned in the video?

[@LeonAnavi]

Yes, I made several compact mechanical keyboards and input devices with XIAO RP2040: ANAVI Macro Pad 12, ANAVI Macro Pad 10, ANAVI Arrows, ANAVI Knob 3 and ANAVI Knob 1. Soon my Nunchuk adapter with XIAO RP2040 will be available at Crowdfunding (crowdfunding campaign). I am also in the final stage of making a computer microphone with XIAO RP2040 called ANAVI Dev Mic (I published a short video about it).

Glad you enjoyed it :) Thank you for the feedback

Don't forget #TinyGo! Awesome being able to programme this (and other) microcontroller using #Go (#Golang). Informative, thanks 😉

[@LeonAnavi]

Yes, absolutely, very good point! I totally agree that modern programming languages like Go and Rust are steadily making their way on embedded devices.

How is #rp2040 RTC powered when the equipment is powered off for extended periods of months and days ?

[@LeonAnavi]

For RTC there are external modules with EEPROM and CR2032 battery which are connected over I2C, aka using pins D4 and D5 for SDA and SCL on XIAO RP2040.

Nice. How much it cost?

[@LeonAnavi]

XIAO RP2040 is available for $5.40 per single unit at seeedstudio.com. They offer discounts for large quantities like 10+: $4.60 www.seeedstudio.com/XIAO-RP2040-v1-0-p-5026.html

Anyone compare this to the SMND21 version? I’ve had SAMD21 boards brick on me running the same project just an LCD on the IC2 ports. Giving the RP2040 boards a shot next..

[@LeonAnavi]

RP2040 is faster as it has a significantly higher clock rate (133 MHz vs 48 MHz) and also more SRAM compared to SAMD21.
