Collection of my PCBs for building Homebrew devices using AskSin++.
soon...
Flexible and small (49x49mm) PCB for AskSin++ devices with multiple power options. Small enough to fit into devices that integrate into german wall socket / switch series.

* I have not tested all parts using this order links, no guarantee that every linked component works. Aliexpress links are affiliate links, so i will get a small commission when you order using this link. This will help me with further projects. Thanks.
- 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.
Inspired from pa-pa HMSensor and HB-UNI-644 from alexreinert. Thanks for your work.
