LEGO Minifigure shaped Mini SAM M4 Board Supports CircuitPython and Arduino

If you are a fan of the Lego movie. Perhaps you have always wanted to use Lego bricks to make something innovative and techy. Then the Mini SAM M4 board is here for you, as it is a LEGO minifigure-sized development board. Additionally, the design and layout of the board is based around the classic 1980’s ‘spaceman’, and is made by Ben Shockley. Although the board is very small, it has a lot of wonderful features. It comes with an analog reference decoupling/filtering capacitors. Also, it has an analog to digital ferrite bead, as well as a debounce circuitry for the reset and user buttons. Furthermore, the board’s software and firmware can be developed using CircuitPython or Arduino. The development board is either based on the Microchip SAMD51G 48-Pin 32-Bit ARM – Cortex M4F MCU (Mini SAM M4), or features the Microchip SAMD21G 48-Pin 32-Bit ARM Cortex -M0+ MCU running […]

SB Components’ Trekko Pico is an open-source, RP2040-powered GPS logger with multi-GNSS support

After the success of their Kickstarter campaign, SB Components has now made the Trekko Pico GPS logger available for pre-order. The Trekko Pico is a small location logger for travelers and outdoor enthusiasts that makes it easy to track routes and record their travels. A Raspberry Pi RP2040 powers the Trekko Pico, providing the programming, connectivity, and data logging functionality. The Quectel GNSS L76K module supports the concurrent reception of GPS, GLONASS (or BeiDou), Galileo, SBAS, and QZSS signals, with 32 tracking and 72 acquisition channels. There is a JST 2-pin connector that can be used to attach an external battery, and the Microchip MCP73831 controller is responsible for battery charging and management. Also, users can slot a coin cell into the holder at the back of the board to power a real-time clock for data backup purposes. Potential applications for the Trekko Pico GPS logger include surveillance, telematics, Geographic […]
