Overview
Bledstripper is an open-source printed circuit board by reelyactive, from the reelyactive/bledstripper-grove repository on GitHub, published under the MIT licence. It is a 2-layer board of 74.5 × 34.5 mm with 30 parts on 55 nets, routed with 195 tracks and 69 vias.
It is built around the MDBT42Q-512KV2, LP2985-33DBV and TXU0104QPWRQ1, with the PJ-202AH among its other parts. Its parts include 7 capacitors, 6 connectors, 3 resistors, 3 diodes and 2 ICs. It belongs with the radio and wireless and lEDs and displays boards and the nRF52 and nRF5x boards of this library.

README.mdbledstripper-grove
Bluetooth Low Energy LED strip controller circuit board with standard Grove connectors. Open hardware under the MIT License.
Overview
The bledstripper-grove combines a MDBT42Q Bluetooth Low Energy SoM and four Grove connectors that can be driven with high-amperage 5VDC power via a standard barrel connector. It simplifies the wireless programming and control of up to four long strips of WS2813 LEDs (or equivalent).
LED Strips
The bledstripper-grove is designed to offer plug-and-play compatibility with Seeed Studio's family of WS2813 LED strips which use standard Grove connectors. The bledstripper-grove is nonetheless compatible with the family of 5VDC addressable LEDs commonly referred to as NeoPixels, strips of which can alternatively be directly soldered to the through-hole connectors of J1-J4 of the board.
Schematic
Key components
The bledstripper-grove comprises the following three key components:
- Raytac's MDBT42Q-512KV2 module, which is based on the Nordic nRF52832 Bluetooth Low Energy IC, and which is Espruino-compatible.
- TI's LP2985-33DBVR 3.3V low-dropout voltage regulator to power the MDBT42Q
- TI's TXU0104QPWRQ1 four-channel voltage-level translator to convert the high-speed LED control signals from 3.3V to 5.0V
BOM selection was made to maximise Shenzhen/Seeed OPL (open parts library) components which include:

Where can I download the Bledstripper KiCad files?
From the reelyactive/bledstripper-grove repository on GitHub, at the commit this page was made from: the board is BoardFiles-bledstripper-grove/bledstripper.kicad_pcb and its schematic BoardFiles-bledstripper-grove/bledstripper.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
