As part of a wider initiative aimed at teaching children the basics of computing and programming, the BBC created the Micro:bit development board (with a little help from some high-profile partners). Unveiled in its final form this Julyafter years in the making, the broadcaster had originally planned to send out the first batch of Micro:bits to teachers this month, before issuing one million of the things to Year 7 students across the country in October. The BBC hassaid today, however, that a problem with the power supply identified on a small number of the microcomputers means that timeline has been pushed back by a couple of months.
