Review of SunFounder TS7-Pro 7-inch touchscreen display for Raspberry Pi 4

Unboxing SunFounder TS7-Pro touchscreen display SunFounder TS7-Pro is a 7-inch touchscreen display designed for Raspberry Pi 4 board and the company sent us one review sample for evaluation. SunFounder has a wide range of Raspberry Pi and Arduino accessories designed for makers, and the TS7-Pro 7 is their latest offering that’s optimized to work with Raspberry Pi 4 and Raspberry Pi 3. Adding a touchscreen display to a Raspberry Pi may be a bit messy with the display or other accessories such as cameras and/or 2.5-inch drive spread on the table, but the TS7-Pro display simplifies all that with a neater assembly. Let’s start the review with an unboxing The package is compact and the display is well-protected with polyethylene foam to reduce the risk of damage during transport. Accessories such as cables, screws and nuts, adapters, an acrylic enclosure, and a screwdriver are also included in the package. Here’s […]

Compact3566 – A Rockchip RK3566 SBC that closely follows Raspberry Pi 3 form factor

We’ve very recently written about Geniatech XPI-3566 SBC powered by Rockchip RK3566 CPU that somewhat follows the Raspberry Pi 3 Model B form factor. Boardcon Compact3566 offers similar features, but it appears to keep exactly the same port assignment as the Raspberry Pi SBC, so it should be compatible with more accessories. The Compact3566 SBC ships with up to 8GB LPDDR4 and 128GB eMMC flash, features Gigabit Ethernet & WiFi 5, four USB 3.0/2.0 ports, HDMI 2.0 output, MIPI DSI and CSI interfaces, the 40-pin GPIO header, as well as extra built-in features such as an M.2 socket for storage, RTC with battery, and a built-in microphone. Compact3566 specifications: SoC – Rockchip RK3566 quad-core Arm Cortex-A55 @ up to 1.8 GHz with ARM Mali-G52 2EE GPU with support for OpenGL ES 1.1/2.0/3.2. OpenCL 2.0. Vulkan 1.1, 0.8 TOPS NPU System Memory – 2GB, 4GB, or 8GB LPDDR4/LPDDR4X Storage 8GB, 16GB, […]

Theengs open-source tools to decode BLE sensors work on ESP32, Raspberry Pi, Android phone, etc…

Theengs is a manufacturer agnostic open-source set of tools to decode BLE sensors and integrate those into smart home and IoT solutions such as Home Assistant with notably support for autodiscovery to automatically create the sensor. Theengs can be installed on various hardware from ESP32 to an Android phone or a Raspberry Pi SBC, and the solution currently supports close to forty BLE sensors from various companies including Xiaomi, Honeywell, and RuuviTag. There are six components: The Theengs Decoder library developed in C++ for portability and translating data from sensors into human-readable data using the JSON format. The Python-based Theengs Gateway acting as a BLE to MQTT bridge for Home Assistant, OpenHAB, and NodeRED integration. It relies on the Theengs Decoder library and publishes the sensors broadcasted BLE information to an MQTT broker. The OpenMQTTGateway is also BLE to MQTT bridge, but instead of targetting Linux-capable hardware like Raspberry […]

CrowPi L Raspberry Pi 4 laptop review – Part 1: Unboxing and teardown

CrowPi L Raspberry Pi Education Laptop Review

Elecrow CrowPi L is an 11.6-inch laptop shell based on Raspberry Pi 4 designed for STEM education with optional electronics modules and tutorials. That’s an evolution of the CrowPi 2 laptop I reviewed in 2020 with a thinner design and more flexible since the electronics modules are optional, so it can serve the market of people just wanting a Raspberry Pi 4 laptop. The company has sent me a full “CrowPi L Advanced Kit” for review with the CrowPi L laptop fitted with a Raspberry Pi 4, as well as the Crowtail Starter Kit for Raspberry Pi. CrowPi L Advanced Kit Unboxing Let’s check out the laptop package first. Since in this design, the laptop comes with a battery, and mine already had a Raspberry Pi 4 installed, I could just turn it on immediately. Accessories include a wireless mouse, a 12V/2A power supply (with USB Type-C plug… this should […]

can2040 project adds software CAN bus to Raspberry Pi RP2040 microcontroller

Raspberry Pi RP2040 can2040 software CAN Bus

The can2040 project is a software CAN bus implementation for the Raspberry Pi RP2040 microcontroller that leverages programmable I/Os (PIO) to achieve reading and writing CAN 2.0B data frames at rates up to 1Mbit per second. Kevin O’Connor, the developer of the project, further explains the implementation uses only one of the two RP2040 PIO hardware blocks, so it is possible for a single Raspberry Pi RP2040 chip to have two separate CAN bus interfaces. Some processing also happens on one of the Arm Cortex-M0+ cores of the microcontroller with the processing time dependent on the amount of bus traffic, and a fully saturated CAN bus at the fastest supported rate of 1Mbit/s may use up to around 30% of that core when clocked at 125MHz, so that should still leave plenty of room for other tasks that may run on the system. I could not find any information about […]
