MAX3421e USB Host FeatherWing test 🖥️ 🔌 ✅

We previously made a jerry-rigged USB Host Wing (https://www.adafruit.com/product/5858) tester based on an ESP32-S2 TFT board (https://www.adafruit.com/product/5300) and a pogo-pin (https://www.adafruit.com/product/394) filled Feather Doubler (https://www.adafruit.com/product/2890) - but for final testing of hundreds of boards off a panel, a nice custom-made PCB is better. This one uses a Metro M0 since our SAMD21 board support package has TinyUSB support - so we can verify if we enumerate the connected USB peripheral. If a vid/pid is found, we're good to go, and beep and blink to indicate the test has passed.

quad-rotary board is getting ready to stock 🔁🎛️💻🔄🔌

this seesaw board converts 4 rotary encoders to I2C for adding a ton of twists. like our other attiny8xx boards, we use a metro m0 to do the programming of the UPDI interface, then communicate over I2C to check each pin is not shorted or open. this will be in the shop soon so don't get your knickers in a twist! https://www.adafruit.com/product/5752

beep beep! new seesaw board tester kit coming thru! 🚚💨📦🔧🎛️💡🎚️🔋💻🔬🛠️💾🚀⏱️🏭🏎️💨

now that we can get chips we're churning out seesaw boards to help with all sorts of common needs - like this I2C to NeoPixel driver converter that uses an attiny816 . it's a 'no solder' way to add NeoPixel support since you can use the pre-attached terminal blocks. we've got our UPDI in-situ programmer running on a Metro M0 https://www.adafruit.com/product/3505 which can set the fuses and burn the firmware so fast, we have plenty of time to take a drive around the adafruit factory.
