Once more dreaming of making things, I started to puzzle over finding small connectors to allow in-circuit programming (ICSP S=serial) of a PIC as well as to allow a couple of push-buttons to be detached.
The standard PICkit 3 connection is a 6way 0.1in header, which is a bit big and a bit tall.
It transpires that there are already two favoured solutions.
Forgive me if I get some names wrong here, but the options appear to be either: Olimex (Molex PicoBlade) or SparkFun (JST ZH) – see below for details.
Most of the usual distributors carry the parts, and even Amazon.co.uk has the JST ZH (search SparkFun ICSP).
Does anyone know which is the more ‘standard’ version, and if there are any more in common or commonish use?
Molex PicoBlade is 1.25mm pitch connector, and Olimex uses a six way version.
Vertical header 53047-0610
Mating housing 51021-0600
Housing contacts 50058-8×00 (28-32awg) (x=0 for reel, 1 for bagged)
Housing contacts 50079-8×00 (26-28awg)
Ratings are 125V 1A (26, 28, 30awg, 800mA for 32awg)
30 mating cycles
9.25mm long (2way 4.25mm, 3way 5.5mm)

JST’s ZH is a 1.5mm pitch connector, and SparkFun uses a five way version.
