Описание
PRoC BLE is a 32-bit, 48-MHz ARM Cortex-M0 BLE solution with CapSense, 12-bit ADC, four timer, counter, pulse-width modulators (TCPWM), Direct memory access (DMA), thirty-six GPIOs, two serial communication blocks (SCBs), LCD, and I2S. PRoC BLE includes a royalty-free BLE stack compatible with Bluetooth 4.2 and provides a complete, programmable, and flexible solution for HID, remote controls, toys, beacons, and wireless chargers. In addition to these applications, PRoC BLE provides a simple, low-cost way to add BLE connectivity to any system.
