flip c3 board front

Voidbox FLIP_C3 is an open-source hardware board powered by an ESP32-C3 WiFi & BLE microcontroller that takes up to 60V DC power input feeding a 5V/2A DC-DC step-down converter and flashed with ESPHome firmware by default for Home Assistant support. The board incorporates a push-in spring release connector which means stranded (ferrules or tinning are suggested) and solid wires can be used in deploying the device in off-grid/battery-powered systems with up to 16s LiFePO4 delivering 48V through the 6-60V input port on the ESP32-C3 board. The onboard WS2812B LED can be used as a null pixel/level shifter for longer strings of addressable pixels. The ESP32-C3 – due to its support for Wi-Fi and BLE connectivity – is a popular SoC for IoT solutions and powers home and industrial automation devices such as NanoCell v2.1, Spark Analyzer, LOLIN C3 Pico, and the LILYGO T-RSC3. It is built for home automation applications […]

Radxa ROCK 5C (Lite) SBC features Rockchip RK3588S2 or RK3582 SoC, WiFi 6, Raspberry Pi PCIe FFC connector

Radxa Rock 5C

First came the ROCK 5B pico-ITX SBC, then the Raspberry Pi 4-sized ROCK 5A board, and now Radxa has launched the Radxa ROCK 5C and 5C Lite single board computers powered by respectively Rockchip RK3588S2 octa-core and RK3582 hexa/octa-core “Lottery” processors. The ROCK 5C (Lite) design is very similar to the ROCK 5A, but there are some notable differences. First, it replaces the two micro HDMI ports with a single HDMI port, then it removes the Key M socket for M.2 wireless modules to make place for a built-in WiFi 6 and Bluetooth 5.4 module plus a Raspberry Pi PCIe FFC connector, and finally, the ROCK 5C does not support an SPI flash module anymore. The specifications of the ROCK 5C and ROCK 5 Lite SBC can be found in the table below. Both processors are new, so let’s have a look. First, how does RK3588S2 differ from RK3588S? They […]

HackBat – DIY open-source hardware Flipper Zero alternative features Raspberry Pi RP2040 MCU, ESP8266 WiFi module, RF transceiver…

HackBat DIY open source pentesting device

HackBat is an open-source hardware pen-testing device designed for hackers and makers and equipped with a Raspberry Pi RP2040 microcontroller, an ESP8266 WiFi module, a sub-GHz RF transceiver, NFC, an OLED display, and more… It’s basically a DIY alternative to the popular Flipper Zero wireless hacking tool, that you can produce and assemble yourself. The Flipper Zero was the victim of its own success with the Canadian government (wrongly) claiming it could easily be used for car theft and planning to ban it (status still unclear right now),  so Flipper Zero alternatives such as the M1 multitool device got some traction as backup solutions with some extra features. But any closed-source device could eventually be banned, something that’s close to impossible for an open-source hardware device like the HackBat although policymakers could still decide to impose heavy fines if they wanted to make this type of device illegal… HackBat key […]

Easily build a robot car with the Car Base Board for the STM32F411 “Black Pill” board

Car Base Board Mounted PCB chassis

The Car Base Board from Applying Microcontroller Solutions is a modular platform for building robot car projects powered by the WeAct Studio Black Pill development board. The Black Pill board is an upgrade to the “Blue Pill 2” board and features the STM32F411CEU6 microcontroller running at 100MHz with 512 KB of flash memory, 128 KB SRAM, and a USB Type-C port for power and programming. The Care Base Board printed circuit board is a base controller that takes hardware expansions such as wireless modules, servos, and sensors to monitor and control a robot car. The onboard headers provide a straightforward way to wire these connections and help prevent a tangled mess (rat’s nest) of wires. The PCB’s design makes it easy to use widely-available, “generic” devices and boards in development and to power all of them with batteries. It also allows the developer to select their favorite wireless communication device. […]
