Electronut Labs has started its Crowd Supply campaign for Blip, a Nordic nRF52840 based development board. With many onboard sensors and systems, the boards are aimed at prototyping and projects in a wide variety of BLE and 802.15.4, wireless application scenarios. It has a programmer and debugger built-in.
Electronut Labs has a series of Nordic Semiconductor SoC projects previously reported on including Papyr, a Bluetooth E-Paper Display and Bluey, a BLE Development board using the Nordic nRF52832, and CNXSoft also published an article comparing several of the Nordic SoC available in development boards for Bluetooth 5 (BLE5).
Blip has a Black magic Probe compatible programmer and debugger built-in, along with a temperature/humidity sensor, ambient light intensity sensor, and a three-axis accelerometer. The board is designed to prototype very low power devices and an ability to add a microSD card slot, to make it a total solution for dev projects.
A low power display device for $24.00.
A handheld gaming device that can be plugged into the Blip dev board that costs $26.00.
All three boards, Blip, Blipboy, and E-Paper displayed can be purchased as a kit for $99.00

Stephen started writing about technology after publishing sci-fi short stories. His first White-Paper, written in 2008, was well received and inspired him to continue writing about technology. Today he writes in the technology space full time, covering a multitude of topics. During the time he wrote part-time he edited hundreds of titles for large publishers, in science and technology. He lives in Staten Island, with his wife and children.
