• That's interesting - the UART should work fine for you. However see: http://www.espruino.com/Puck.js#serial-cĀ­onsole

    You need to have the UART RX pin pulled high (the idle state) when the firmware boots up. Enabling the UART uses lots of power (the chip can't sleep properly), so it's not done automatically.
