iOS Development

The initial PCB design was finished on October 17th, but since it takes some time to produce and ship it I finally received it yesterday. After tweaking some design faults with isolated copper wire I got the RFID Reader working after about three hours. Well the firmware was already written and the WT12 configuration just needed to be downloaded to the module. After fixing, soldering, measuring voltages, flashing firmwares here is the final assembled “Bluetooth RFID Tagreader”.

After some Bluetooth RFID Reader prototypes I created a new board which is designed to fit into an enclosure which will be printed by a 3D print service. The Reader can be connected to iOS Devices and sends the UID of a MIFARE Tag as text string into any iOS app which is capable of handling texts. A tactile switch is added to the reader as well, in order to unhide/hide the on board keyboard on an iPhone or iPod Touch.
