Other key parts include the SE5218 and TXB0104QPWRQ1. By type, the board carries 7 capacitors, 2 ICs, 2 jumpers, 2 relays and 1 resistor.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
Hardware design, BOM, gerbers and 3D files for MicroSD-breakout designed by Soldered Electronics.
A module which enables the use of micro SD cards with Arduino via SPI communication. You can save various types of data on the SD card, create logs, read the information from it or perform various actions.
All Soldered Electronics hardware designed in KiCAD, and repositories are organized in the following way:
- CAD folder - contains KiCAD files (Schematics, Board, Panel Board), sorted by version. Change log lists all changes between versions. - OUTPUTS - contains useful files, such as Bill of Materials (BOM), PDF of schematics, 3D .step file of the board and gerber files, sorted by…
