Qualcomm has canceled its upcoming Windows Mini PC, the Snapdragon Dev Kit, in what could be a blow to some Arm developers. The $899 Mini PC wasn't intended for general use, but to help developers develop Windows applications that were natively compatible with chips manufactured by semiconductor giant Arm.

In late July, Qualcomm quietly debuted a Qualcomm Snapdragon Dev Kit sold by Arrow. This week, Qualcomm and Arrow have recalled those Dev Kit units.

Qualcomm has canceled its Snapdragon Dev Kit, the miniature Windows on Arm PC that was originally supposed to ship in June. In an email to customers, Qualcomm said the mini PC “has not met our usual standards of excellence” and orders will now be refunded.
