Electronut Labs recently released their open source Nordic nRF52832 development board that can be used for your next BLE project. This tiny board can be plugged on a breadboard or soldered on a PCB and provides additional value from just using the BLE module directly as it includes...

Over the years FPGAs have become readily available to the maker community. They are now more accessible than ever as many development boards has seen the light. It’s now possible to embed a soft-core MCU into an FPGA  rather than using a hard-core ASIC MCU and here is where PulseRain...

4D Systems, the manufacturer of intelligent graphics solutions, has announced a new 0.9” smart display module as part of the ‘IoD-09’ series. This series is a set of small full-color TFT display modules that feature the Espressif ESP8266 SoC. It also comes with microSD card slot...

An ECG patch with HRV monitoring that's open source, affordable, and Wi-Fi/Bluetooth connected. HeartyPatch is a completely open source, single-lead, ECG-HR wearable patch with HRV (Heart Rate Variability) analysis. It is based on the popular ESP32 system-on-a-chip. By using low-cost,...
