Raspberry Pi Build HAT

Story

Raspberry Pi today announced the Raspberry Pi Build HAT, a brand-new device that makes it simple to connect LEGO® TechnicTM motors and sensors to Raspberry Pi computers for the first time. Raspberry Pi was created to provide young people, teachers, and makers with exciting and innovative learning opportunities.

The Raspberry Pi Build HAT is an add-on board created in partnership with LEGO® Education that allows Raspberry Pi computers to control LEGO® TechnicTM motors and sensors.

The BuildHAT is a board that allows a Raspberry Pi host to communicate with up to four LEGO LPF2 (LEGO Power Functions version 2) devices. A wide range of actuators and sensors are supported by LPF2. The HAT's firmware handles the LPF2 devices' hard real-time needs, such as monitoring for connection and disconnection events and interrogating devices to discover their capabilities and characteristics.

The 'command port, ' a 115200 baud serial interface with eight bits per letter, no parity, and one stop bit ('8N1'), connects the HAT to the Raspberry Pi host. There is no way to regulate the flow. Because the command port protocol is fully written in plain text, it is absolutely viable to use a terminal emulator on the host to communicate with the HAT manually.

When playing with the HAT in this fashion, it's helpful to activate echo mode so you can see what you're typing: see the echo command explanation below. Also see the plimit command, which is required for several procedures to operate properly.

The Raspberry Pi Build HAT add-on board attaches to your Raspberry Pi's 40-pin GPIO header and was created in partnership with LEGO® Education to make controlling LEGO® TechnicTM motors and sensors with Raspberry Pi computers simple. All 40-pin GPIO Raspberry Pi boards, including the Raspberry Pi 4 and Raspberry Pi Zero, are compatible with Build HAT. It may also be utilised with Raspberry Pi 400 with the addition of a ribbon cable or other extension device.

It has four connections for SPIKETM Portfolio LEGO® TechnicTM motors and sensors. A distance sensor, a colour sensor, and a flexible force sensor are among the sensors offered. The angular motors are available in a variety of sizes and include built-in encoders that may be used to determine their location.

The Raspberry Pi Build HAT power supply, which is sold separately, is designed to power both the Build HAT and the Raspberry Pi computer, as well as any other LEGO® TechnicTM devices attached to it.

The Build HAT is supported by the LEGO® Education SPIKETM Prime Set 45678 and SPIKETM Prime Expansion Set 45681, both of which are available separately through LEGO® Education resellers.

Easy-to-use Python library to control your LEGO® TechnicTM devices
Controls up to 4 LEGO® TechnicTM motors and sensors included in the SPIKETM Portfolio
Onboard RP2040 microcontroller controls low-level management of LEGO® TechnicTM components
External 8V PSU supplied separately to power both Build HAT and Raspberry Pi
Compatible with any Raspberry Pi computer with a 40-pin GPIO header

This is a fantastic solution that extends the life of Lego's costly kits. This is a wonderful approach to teach Python with recognisable components if your wallet can take it.
