About the AskSinPP PCB

AskSinPP is an open source AVR/Arduino PCB design by c-klinger, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 48.5 × 48.5 mm, with 40 components from 28 distinct parts.

Its main chip is the ATmega328P-A, from the AVR/Arduino family. Other key parts include the CC1101, MAX1724 and HT7533-1. By type, the board carries 13 capacitors, 9 resistors, 6 connectors, 4 ICs, 2 transistors and 2 switches.

Collection of my PCBs for building custom Homematic devices using AskSin++

\ 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.*

Inspired from pa-pa HMSensor and HB-UNI-644 from alexreinert. Thanks for your work.

AskSinPP: common questions

What microcontroller does the AskSinPP use?

The AskSinPP is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the AskSinPP PCB?

The AskSinPP measures 48.5 × 48.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AskSinPP?

40 components, from 28 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the AskSinPP design files?

From the c-klinger/AskSinPP-PCB repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the AskSinPP design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the AskSinPP without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
