BANDIT PC32 is a Raspberry Pi RP2350-powered keyboard computer that runs a graphically-oriented version of the ColorForth programming environment. The BANDIT PC32 is primarily aimed at on-the-go use for programming video games. The custom, 32-key split keyboard takes up most of the build, with a 3.2-inch 320 x 240 capacitive display in the center. It also features an HDMI port for connecting a larger external display. The 48-pin GPIO is divided into two female headers and can be used to interface with other devices directly. This is the second version of the Bandit standalone computer, building on an early prototype based on the RP2040 microcontroller. We have seen several interesting RP2350-based products like the Inky Frame 7.3”, 4D Systems display modules, and Jumperless V5 programmable breadboard. However, this is the first RP2350 standalone computer we have come across. It shares some similarities with the ESP32 Rainbow. BANDIT PC32 ColorForth specifications: […]

ESP32-based Waveshare DDSM Driver HAT (B) for Raspberry Pi supports DDSM400 hub motors
Waveshare has recently launched DDSM Driver HAT (B), a compact Raspberry Pi DDSM (Direct Drive Servo Motor) motor driver designed specifically to drive the DDSM400 hub motors. This board is built around an ESP32 MCU and supports wired (USB and UART) and wireless (2.4GHz WiFi) communication. Additionally, the board features a physical toggle switch, which lets it choose between the ESP32 control or USB control modes. On ESP32 control mode you can control the device through a built-in web application. In the USB control mode, the motor driver can be controlled via USB from a host computer sending JSON commands. An XT60 connector is used to power the board, and programming is done through a USB-C port that connects to the ESP32. The board is suitable for robotics projects, especially for mobile robots in 6×6 or 4×4 configurations.

Ditronix’s IPEM PiHat turns your Raspberry Pi into a mains power energy monitor (Crowdfunding)
The IPEM PiHat is a HAT (Hardware Attached on Top) board for the Raspberry Pi that turns the single-board computer into a mains power energy monitor with four CT clamps. It provides an accurate way to track energy usage in home, office, and solar energy systems and is compatible with single-phase, two-phase, and three-phase electrical systems. The Raspberry Pi-based power energy monitor uses CT (current transformer) cable clamps to sample and measure data which can be used to report and analyze electric energy usage. This data can be used to save and divert energy to reduce costs and inefficiencies. The system is easy to set up and does not require a professional electrician. It uses a CT current clamp clipped over the building’s main power cables and connected to the local mains circuit for voltage and frequency measurement. The add-on board comes in two variants: IPEM PiHat and IPEM PiHat […]
