Jarrett published a new project. It is a battery powered ESP32 module. I’ve been working on an ESP32 module. Part of the problem I’ve been seeing with inexpensive IoT dev boards, is that the design around the power system hasn’t been very good. Here’s my attempt to fix that....

Adding wireless charging to furniture and other consumer goods is a nice way to add some oomph to an otherwise boring product. NXP’s NXQ1TXH5 provides an interesting, albeit difficult-to-prototype way around the problem. Creating a Qi-compatible is as easy as assembling the example...

The EVALSP820-XS is a compact and easy to use evaluation board for the STSPIN820, the world's smallest 45 V microstepping motor driver rated at 2.5 A. It provides a very compact solution to evaluate the performance of the STSPIN820 stepper motor driver with a minimum set of additional...

The Grove - Infrared Temperature Sensor Array (AMG8833) is a high precision infrared array sensor which based on advanced MEMS technology. It can support temperature detection of two-dimensional area: 8 × 8 (64 pixels) and maximum 7 meters detection distance. We provide both Arduino...

Process computer designs usually start out with an accelerometer. As reliability problems creep in, making the switch to a more “professional” solution is beneficial. Accelerometers are based on the MEMS principle: instead of being a purely solid-state affair, the inside of the...

Avalue recently announced a Linux-friendly 3.5" ECM-CFS Single Board Computer with a choice of Intel’s latest 8th Gen “Coffee Lake” S-series processors. It also features triple display support, 2x GbE, 4x USB 3.1, 2x SATA, and mSATA. This SBC is considered as the world's first...

Pi Supply has launched a new series of IoT LoRa Boards on Kickstarter that work with Raspberry Pi, and Micro:bit. They include an IoT LoRa Gateway HAT board with a price of £120 ($157) and a LoRa Node pHAT node board for £25 ($33) price. The boards support any 40-pin Raspberry Pi, and...

Coinciding with the BT815 and BT816 advanced graphics controller ICs being ramped up into volume production, Bridgetek has introduced a series of accompanying entry-level development modules. Supporting a range of different display configurations, the compact (54.1mm x 85.60mm) VM816C...
