Warning: Some uBitx kits shipping with incorrect female connectors

KF2510 headers in uBITx

There are two 8 pin wiring male headers in the kit – one on the main uBITx board and the other on the Raduino.  Today, Arvo KD9HLC started assembling the wiring on his kit.  He found that the female plugs didn’t match the headers on the board.  After a bit of head scratching and further investigation he found that the female header plugs with flying leads only had 7 pins!

It is likely that other kit purchasers may have the same issue.

These headers are of KF2510 type, widely used in China and are very affordable.  Sets of 50 male/female pairs of 2, 3, 4 and 5 pins are available for about US$3 ex China if you can wait.  And 8 pin females can be found on the various Chinese merchant sites as well.   However, these headers are a bit harder to source in the US.   In NZ and Australia they can be sourced from Jaycar.

THe uBITx kits come with  2 x 8 pin, 1 x 3 pin, 1 x 2 pin wiring harnesses with KF2510 female plugs.   The Raduino unit connects to the main board with a 16 point pre-soldered header.

HINT:   You can substitute ordinary Dupont header strips or single female pins.  They won’t be polarised, so you will need to be careful making connections.
