I made a business card that played Tetris, plus various animations on a 10x18 LED matrix with 2 brightness levels a few years back for clients. Went down well :) It uses an ATMega328pb 8-bit microcontroller, running at 8mhz, running from a 2016 coincell. It doesn't flicker in real life 😁 #gamedev

#lowpower with #esp32 works well, except for the previously mentioned issue. Lets go 'classic' atmega328 and nrf24. We go from power down @ 7uA to sleep @ 11uA. But most importantly the 368mA peak is now 30mA. With some tweaking, we send a sensor sample every 90s @ 14uAh. Can we improve this?

#lowpower nrf24 sensor node, trying to get the longest battery life. De atmega328pb works down to 1.8V@1MHz, but what about sensors and nrf24? an SHT31 >= 2.2V, nrf24 >= 1.9V, but range drops. In practice around 2.5V works well. This (incl. sensor) gives us a year on a cr2032 @ 2m sensor interval.
