#arduinodesign

We're testing out prototypes of a new Metro https://www.adafruit.com/search?q=metro RP2040 , while the 'classic Arduino shape' is not as popular these days with dev boards as it used to be, we like the roomy layout, with lots of socket headers, and plenty of space for accessories like a MicroSD card socket with both SPI and SDIO pinout, SWD debug port, Stemma QT, and 12V DC power port. our last test is always to plug in our 2.8" captouch TFT shield https://www.adafruit.com/product/1947 because it tests both SPI and I2C. this passes and since all the GPIO are accounted for, we just have to wrap up the silk and it's off to fabrication!
