The RootMaster is a Raspberry Pi Zero 2W-based hydroponic automation system designed to precisely manage water and environmental conditions. The solution also integrates an STM32G4 microcontroller to handle real-time operations such as controlling pumps and peripherals, managing sensors, and processing data from external sensors like water level indicators. It also generates PWM signals to control the power of connected devices and handles communication with external modules through a CAN FD interface. While STM32 handles hardware-level tasks, the Raspberry Pi Zero 2W manages high-level control and user interaction. The RootMaster can be programmed with Python, C, C++, or other programming languages and is useful for applications like Hydroponics automation, water circulation, and environmental control. RootMaster specifications MCU – STMicro STM32G473 32-bit Arm Cortex-M4 microcontroller @ 170 MHz for real-time operations Main controller – Compatible with Raspberry Pi Zero 2 WH for GUI and other interfaces Sensors pH sensor for nutrient solution […]
Clipper HAT Mini – A Raspberry Pi 4G LTE pHAT with Qwiic/STEMMA QT connector
Pimoroni Clipper HAT Mini – also called “CLIPPER LTE Mini HAT” – is a Raspberry Pi 4G LTE pHAT that can use mobile data for remote projects where WiFi connectivity is unreliable or unavailable. The HAT is built around a SIMCom A7683E LTE Cat 1 modem with support for frequency bands B1/B3/B5/B7/B8/B20/B28, offering uplink speeds up to 5 Mbps and downlink speeds up to 10 Mbps. Other key features of this HAT include a SIM card slot, an SMA antenna connector (antenna sold separately), two user buttons, indicator LEDs, and a Qwiic/STEMMA QT connector for I2C modules. The board is designed to attach to Raspberry Pi (Zero) via a pre-soldered socket header and includes introductory global data coverage via a 1NCE SIM card. These features make this device suitable for IoT projects, mobile data collection, and remote-controlled devices in varied environments. Raspberry Pi LTE 4G HAT Specifications Compatibility – Supports […]
$7 Raspberry Pi Pico 2 W board launched with 2.4 GHz WiFi 4 and Bluetooth 5.2 wireless module
As expected, the Raspberry Pi Pico 2 W – the wireless version of the Raspberry Pi Pico 2 – is now available with an extra 2.4GHz WiFi 4 and Bluetooth 5.2 wireless module at an official price of $7. We’ll go through the specs and perform a mini review in this post trying out both WiFi and Bluetooth code samples. It’s not the first Raspberry Pi RP2350 with WiFi and Bluetooth we’ve seen, as Pimoroni introduced the Pico Plus 2 W board with an RP2350B MCU and Raspberry Pi RM2 Wi-Fi and Bluetooth module, and iLabs launched the Challenger+ RP2350 WiFi6/BLE5 board relying on ESP32-C6 wireless module. However, the Raspberry Pi Pico 2 W is the official board, is cheaper, and will certainly be the most popular/widely used.
