Comments
- Minimum size of SMD components is 1206: it's possible to solder the PCB by hand.
- 3 Power Options
- Poweroption 1: Step-Up DC-DC Converter MAX1724EZK33: 0.8V to 5.5V Input Voltage Range. Best for Battery powered devices.
- Poweroption 2: Linear Voltage Regulators (LDO) HT7533: 5-12V Input Voltage Range. Best for most external DC Power Supply. Jumper J2 needs to be shortened for this Poweroption.
- Poweroption 3: External 3.3V Supply. Jumper J1 and J2 needs to be shortened this Poweroption. No fuse or reverse polarity protection!
- Assembly and use only one of the Power Options at time.

Questions
How big is the Hb uni-328p small PCB?
It measures 48.5 × 48.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hb uni-328p small use?
44 parts, built around the ATMEGA328P-AU, CC1101RGP, HT7533-1 and LQH43CN100K03L. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hb uni-328p small KiCad files?
From the c-klinger/AskSinPP-PCB repository on GitHub, at the commit this page was made from: the board is hb-uni-328p-small/hb-uni-328p-small.kicad_pcb and its schematic hb-uni-328p-small/hb-uni-328p-small.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hb uni-328p small design in my own project?
Its repository states no licence, so its author keeps all rights: ask c-klinger before reusing the design.
