As a carrier board for the Raspberry Pi Compute Module 4 (CM4), Piunora is essentially a tiny version of the Raspberry Pi 4 Single Board Computer (SBC) with added flexibility to accommodate custom form factors. A Qwiic/Stemma-QT-compatible connector makes it quick and easy to use I²C sensors—from Adafruit, SparkFun, and others—via Python
With more than 3 years’ cooperation of the designer, Timon, Makerfabs taken in the productions of the board, as follows: ● PCB production: There high spec/quality demands on the silkscreen, after communication with the designer/PCB factory back and forth many time, we succeed to make the silkscreen with Silkscreen printing, meets the designers silkscreen requests. ● Components collecting: Makerfabs gather the components with good price, especially the connectors Steel Spacer, that need to be imported. ● Components soldering: There 2x50 dual board-to-board connectors, with 0.4mm pitch, and HDMI/USB Type-C connectors, Makerfabs redesigned high precise Stencil to ensure the soldering pass-rate; besides, mix usage of Medium temperature/ High temperature solder paste, to ensure the soldering quality of ws2812 and other components. ● Testing: Working together with the designer, Makerfabs help on the testing jig designing, testing firmware adjusting(Python). ● Product assembly& Shipping: All products will be packaged carefully with customer’s customized cases and ship to re-sellers directly, Adafruit/Mouser… with re-sellers’ packaging requests.
1. High quality requests on PCB silkscreen 2. Dual row Connector soldering with 0.4mm pitch 3. Testing jig designing, testing firmware co-designing 4. Coordinate with other producers, such as case factory/label producer, to make final product with case
