 # Hardware design
 
 * The PCB design is published on: https://lceda.cn/ThomasTempe/Pocket_Musical_Instrument
- * The PCB is two-sided, but all the solderable components are on the same side. It is designed to use 0402 and QFN components, and is unfortunately not practical to home-etch or hand-solder ; however, you can order the PCB for a low price directly from https://szlcsc.com. If you have a China address, you can even have them do prototype pick-and-place soldering for most components (still requires SMT hand-soldering skills to finish, though).

  * It has a LiPo battery that lasts a few hours, and a USB port for charging, and ultimately for MIDI over USB.
