Description
ReadRing prototype PCB This board takes power from nRF52840 Dongle to drive a 80VDC boost converter and control 9 piezoelectric braille actuators by means of Common Emitter / Common Collector Cascades. It receives braille code from smartphone via Bluetooth and can be navigated with 4 buttons. ReadRing is an affordable wearable braille smart device to tackle problems of literacy and accessibility of blind people and promote independent living.
