Since then Gordon Williams, the chap behind the Espruino, has produced several other boards including the Espruino Pico—which also raised on Kickstarter—and the Puck.js an “…intelligent Bluetooth button.” However his latest board, the Pixl.js, is a bit of a departure from his previous products.
The Pixl.js is a smart Bluetooth LE connected display based around the Nordic Semiconductor nRF52832, a 64MHz Arm Cortex-M4 with 64kB of RAM and of 512kB Flash.
Gordon was kind enough to send me an early production prototype of the Pixl.js back at the end of April, just before I got on a plane to head out to States for a month of conference travel. Regretfully I didn’t manage to fit it in my carry on, so it’s been sitting on my desk ever since, waiting for me to have a day to look at it properly.
While looking nothing like his previous board, the Puck.js, the new Pixl.js is evidently based around the same hardware as the Puck and since I got my prototype Williams has done a lot of work documenting the new board.
