Seeed Studio XIAO nRF52840 Integration Project

Project featuring stopwatch based on Arduino nano and DYI 7 segment clock with max7219 and ULN2803A transistor array. For comunication project uses nRF24L01. #Arduino #Nano #Shield #project #nRF24 #max7219 #ULN2803A #Stopwatch #Firefighting_sport

A Bluetooth Power Logger utilizing Seeed Studio's XIAO nRF52840 uC Power Monitoring handled using the INA260 IC, this design should be safe for usage under 36V 8A. Higher current rating will require larger trace widths on the main power trace. Attach your Power Supply to V+ and GND. Then attach your loading device to LOAD+ and GND.

The Arduino Nano 33 BLE is an evolution of the traditional Arduino Nano, but featuring a lot more powerful processor, the nRF52840 from Nordic Semiconductors, a 32-bit ARM® Cortex™-M4 CPU running at 64 MHz.

The Argon is a powerful Wi-Fi enabled development board for Wi-Fi networks. It is based on the Nordic nRF52840 and has built-in battery charging circuitry so it’s easy to connect a Li-Po and deploy your local network in minutes. #Particle #Argon #Template #Iot #Project-template
