BastBLE
About the BastBLE PCB
BastBLE is an open source PCB design by ElectronicCats, published on GitHub. It is a 2-layer board measuring 50.8 × 22.9 mm, with 35 components from 22 distinct parts.
Other key parts include the AP2112K-3.3, E73-2G4M08S1C, MCP73831-2-OT and W25Q32JVSS. By type, the board carries 10 capacitors, 9 resistors, 5 connectors, 4 ICs, 3 diodes and 1 transistor.
It belongs with the iot & wireless and dev boards & breakouts designs in this gallery.
From the project
Bast BLE is all the best in the world format Feather and BLE with a Nordic NRF!, Feather pin to pin compatible with a USB port type C
Bast BLE is all the best in the world format Feather and BLE with a Nordic NRF!, Feather pin to pin compatible with a USB port type C.
Bast-BLE is supported in the Arduino development environment and Circuit Python coming soon
We love all our Feathers equally, but this Feather is very special. It's our first Feather that is specifically designed for use with CircuitPython! CircuitPython is our beginner-oriented flavor of MicroPython - and as the name hints at, its a small but full-featured version of the popular Python programming language specifically for use with circuitry and electronics.
