Makerdiary Releases Pitaya Go IoT Development Board Based on Nordic’s nRF52840 SoC

Makerdiary one of the most innovative startups in the IoT devices space which are known for a series of development boards like the nRF53832-MDK V2 IoT module, and the nRF52840 MDK USB dongle, among others, recently launched a new addition to their impressive line of Nordic’s nRF528xx-series of SoCs based IoT devices, called; Pitaya Go IoT Development Board.

The Pitaya Go combines the Nordic’s nRF52840 SoC with an Arm Cortex-M4 (256Kb of RAM/1Mb of Flash) with FPU, and a Microchip’s ATWINC1500B Wi-Fi controller, in a 60.96mm x 25.4mm x 7.6mm package. This combination brings in a wealth of features which drives the array of connectivity options and high performance associated with the Pitaya Go.

Some of the features of the Pitaya Go include;
