New Half Day: Raspberry Pi LEGO HAT

The Raspberry Pi Basis have been busy little bees for the final couple of years producing their very own silicon, new boards and now in collaboration with the LEGO Schooling crew a new HAT to connect to the LEGO SPIKE education platform. This new HAT board will work with each Raspberry Pi board with a 40-pin GPIO header.

Based mostly on the RPI2040 microcontroller, it makes an attention-grabbing detour away from dumb slave boards, though it appears just like the firmware is closed (for now) so that you’ll need to make do with the pre-baked capabilities and speak to it with the provided python library.

In line with the documentation, the communication between the Pi and the RPI2040 nestled beneath the HAT PCB is plaintext-over-serial, liberating up the vast majority of the GPIO pins for different makes use of. The board makes use of a floor mount pass-through kind header which permits pins from the Pi to protrude by way of the PCB, permitting stacking extra HATs on high. Curiously they determined to mount the PCB with lively components going through down, giving a flat rear floor to park issues on. We suspect that call was made to enhance entry to the LPF2 connectors, particularly in the event that they have been floor mount components.

Compatibility with LEGO {hardware} can be totally documented, together with the Spike Education portfolio, which contains motors, a color sensor, drive sensor, and a distance sensor amongst others. Some components from the mindstorms robotic inventor equipment as are additionally supported. LEGO have additionally launched a brand new half, that they're calling the ‘maker plate’ which is particularly designed for mounting ‘SBCs’ however doesn’t specify which of them. Clearly it appears like it should take Pi3/4 board, however we’ll depart it to them to make clear different help.

A brand new higher-power energy provide brick can be launched, which feeds 8V into that barrel jack you will have observed, as you could bear in mind, LEGO motors can pack fairly a punch and making an attempt to energy these from the Raspberry Pi GPIO header will solely finish in frustration.

We’ve seen an infinite array of LEGO hacks through the years, and this new product shouldn't be the primary hackable resolution we’ve seen. Simply checkout this Open Source Evlōno One for starters. This new product nonetheless is a pleasant instance of a fairly open firm moving into mattress with a longtime participant and producing one thing cool and that may be a good factor.

Thanks [Qes] for the tip!
