We ship all of our nRF52840 (https://www.adafruit.com/search?q=nrf52840) bluefruit boards with a UF2 bootloader and test program: and since these boards are quite old we haven't updated the tester shipping firmware in a long time! however, we have to fix that now because the latest version of circuitpython needs newer bootloader code due to it's chonky size. so we're going back to each tester and updating it. we just did the Feather nRF52840 (https://www.adafruit.com/product/4062), next up is the itsybitsy (https://www.adafruit.com/product/4481)!
