Starfish PnP machine control board combines Raspberry Pi RP2040 MCU with TMC2209 motor drivers

StarFish Raspberry Pi RP2040 PnP control board

We’ve already seen the Raspberry Pi RP2040 MCU in a 3D printer controller board, so it should come as no surprise that the dual-core microcontroller also found its way into a Pick-and-Place (PnP) machine control board. Designed by Thea Flowers, the Starfish board leverages the RP2040 MCU capabilities to control three Trinamic TMC2209 motor drivers, MOSFET drivers to control DC vacuum pumps, two vacuum sensors, and offer RS485 and I2C connectivity for feeders and peripherals respectively. Starfish specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller at up to 133 MHz with 264 kB of embedded SRAM Storage – QSPI flash Motor drivers – 3x TMC2209 drivers for X, Y1, and Y2 MOSFETs – 2x MOSFETs to control the 2x vacuum pumps Valve drivers – 2x TI DRV120 single-channel relay, solenoid, and valve drivers to control two pneumatic solenoid valves Sensors – 2x CFSensor XGZP6857D I2C pressure sensor modules […]

Giveaway Week 2022 – Pico:ed Smart Cutebot Kit

The third prize of this year’s giveaway week comes courtesy of ELECFREAKS which offers a Cutebot Pico:ed kit based on the Pico:ed board with a Raspberry Pi RP2040 microcontroller and following BBC Micro:bit form factor. The kit also includes two high-speed motors to drive two wheels, ultrasonic & distance sensors, two RGB LED lights and clearance lamps on the bottom, two line-tracking probes, and an active buzzer used as a horn. It is powered by three AAA batteries. The company initially me asked me if I wanted to review the board/robot, but since I may not have the time to do so, I asked whether they wanted to be included in our yearly giveaway week which they accepted. The company provides instructions to program the robot with “Micro block” visual programming IDE, C++, and CircuitPython. You’ll find resources to get started and eight projects for the robot in the Wiki. […]

Giveaway Week – e-con Systems e-CAM20_CURB camera

Today, we’re giving away the e-con Systems e-CAM20_CURB is a 2.3MP color camera with a global shutter that is designed to work with Raspberry Pi 4 SBC. The camera is based on ON Semiconductor AR0234CS CMOS sensor and supports uncompressed video at 1920 x 1200 (2.3MP) up to 60 fps, 1920 x 1080 (Full HD) up to 65 fps, and 1280 x 720 (HD) up to 120 fps. I just completed the e-CAM20_CURB camera review with Raspberry Pi 4 last weekend and found the video smoothness and quality to be much better than most cameras I’ve tried when there is motion, even in relatively dark scenes, since motion blur and artifacts are reduced. The company provides Yocto Linux and Raspbian/Raspberry Pi OS images with V4L2 drivers and Gstreamer tools, and the camera was fairly easy to use with the Yocto image thanks to the useful documentation provided with the kit.

RP2040 firmware converts Raspberry Pi Pico into a an I2C to USB bridge

Nicolai Electronics’ rp2040-ic2-interface open-source firmware for the Raspberry Pi Pico (or other Raspberry Pi RP2040 boards) converts the board into an I2C to USB bridge to connect any I2C sensor or module to a PC or other hardware without GPIOs. The firmware implements the USB protocol expected by the I2C-Tiny-USB kernel driver used by the original I2C-Tiny-USB project for Microchip ATMega 8-bit AVR microcontrollers. The RP2040 is however not a fork of the original project, but instead a complete re-implementation of the firmware. You’ll need to connect your I2C sensor, display, or another module to the SDA (GPIO 2) and SCL (GPIO 3) pins of the Raspberry Pi RP2040 microcontroller and flash the “pre-release” firmware to the board. You’ll find it together with the source code written in C language on GitHub. Note the project has a “proof of concept status” and more testing is needed to make sure that […]
