SunFounder PiPower 3 kit is a UPS solution for the Raspberry Pi 5 SBC

SunFounder PiPower 3 kit is a UPS solution designed to work with the Raspberry Pi 5, other Arm SBCs, or even MCU boards like Arduino UNO and Raspberry Pi Pico. The board delivers a stable 5V/5A output, and a 32-bit CH32V003 RISC-V microcontroller takes care of power management and battery level reporting to make sure the Raspberry Pi 5 keeps running when a power failure occurs and shutdowns gracefully when the battery level is low. The kit comes with two 18650 2,000mAh batteries that connect through a 2-pin connector, and all accessories – standoffs, acrylic case, and fan – for assembly with the Raspberry Pi 5, or other compatible boards like the Pi 4, Banana Pi BPI-M5, Radxa Rock Pi E, Orange Pi 3B, and others. PiPower 3 kit specifications: 32-bit CH32V003 RISC-V microcontroller supporting I2C communication Input – 5V/5A via USB Type-C with PD support Output – 5V/5A […]

The Pico Display Base Board offers a simpler way to create Raspberry Pi Pico LCD projects

The Pico Display Base Board is a printed circuit board from Applying Microcontroller Solutions that provides a platform for building Raspberry Pi Pico-based display projects. It works with a Raspberry Pi Pico board and an LCD screen based on the Solomon Systech SSD1963 display controller. The Pico Display Base Board features a 40-pin header (Display Port) which connects to GPIO on the Pico to provide an 8-bit parallel interface for the display and SPI pins for the touchscreen and integrated SD card. It supports various display sizes from 4.3 inches up to 7 inches. Displays up to five inches can be powered directly by the Pico. A jumper block on the board can be used to pass power to the LCD and wire the display’s optional flash chip to the Pico. A USB-C port on the board can provide an alternative power source for larger displays. It also has male […]

7-inch ESP32-S3 touchscreen display exposes RS485, CAN Bus, I2C, UART, and analog sensor interfaces

Waveshare ESP32-S3-Touch-LCD-7 is an ESP32-S3 powered WiFi 4 and Bluetooth 5 LE 7-inch touchscreen display with plenty of expansion interfaces such as RS485, CAN Bus, I2C, UART, and Analog input that can be used to develop various HMI applications We’ve written about many ESP32 boards with displays, but most are small displays under 3-inch, and larger displays are more of a rarity except for ESP32 e-Paper displays such as the Inkplate 10 or LILYGO 7.5-inch e-Paper display. Most are based on ESP32-S3 since it comes with an RGB LCD interface, and the only other 7-inch ESP32-S3 touchscreen display we’ve looked into is the Elecrow 7.0-inch display with specifications similar to the Waveshare ESP32-S3-Touch-LCD-7, but fewer I/O headers. Waveshare ESP32-S3-Touch-LCD-7: Wireless module – ESP32-S3-WROOM-1 MCU – ESP32-S3N8R8 dual-core Tensilica LX7 up to 240 MHz with 512KB SRAM, 8MB PSRAM, 8MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth LE 5 […]

Inkplate 6 MOTION STM32-powered wireless e-paper display offers higher resolution and faster refresh rates (Crowdfunding)

The Inkplate 6 MOTION is a new product from Soldered Electronics in their Inkplate series of wireless e-paper displays. It is a 6-inch e-paper display with a partial refresh rate of 11fps which reduces obvious latency in rendering dynamic content such as videos, animations, and scrolling text. The display is driven by an STMicroelectronics dual-core STM32H743 microcontroller, with an ESP32-C3 as a secondary processor. It features Wi-Fi and Bluetooth for networking and a host of peripheral interfaces for physical connectivity. It includes several sensors such as a rotary encoder for quick navigation, a gravitational accelerometer with a gyroscope for tracking device orientation, and a motion detection sensor. We covered the original Inkplate 6 display when it launched on Crowd Supply in 2019. The Inkplate 6 is much less expensive than the new model but has a lower screen resolution (800 x 600 px) and slower refresh rates (256ms). Furthermore, it […]

Raspberry Pi Zero HAT compatible Quectel BG95-M3 Zero cellular IoT board runs QuecPython MicroPython firmware

Quectel BG95-M3 Zero SBC with QuecPython MicroPython firmware

Waveshare BG95-M3 Zero is a Raspberry Pi Zero-sized SBC based on Quectel BG95-M3 cellular IoT module with LTE Cat M1 (eMTC), LTE Cat NB2 (NB-IoT), and eGPRS connectivity as well as GNSS. The board supports Raspberry Pi HATs and ships with Quectel’s QuecPython MicroPython firmware for easier programming. We’ve previously covered various SBCs and Raspberry Pi HATs based on Quectel modules for cellular IoT and GNSS connectivity with the likes of Olimex NB-IoT-Devkit (with a BC66 module), S-2Connect Creo evaluation kit, Sixfab 5G Modem HAT, and others. Olimex BC66 board supports Arduino programming, but most of the other boards rely on a host processor. Waveshare’s BG95-M3 Zero is a standalone SBC offering compatibility with Raspberry Pi Zero (p)HATs, and Quectel also developed its own MicroPython firmware called QuecPython that works with several of their modules, including the BG95-M3. BG95-M3 Zero specifications: Cellular IoT Module – Quectel BG95-M3 CPU – Arm […]
