Zest_Core_nRF52832-QFAA

Overview

The Zest_Core_nRF52832-QFAA is an electronic development board for 6TRON open source platform based on nRF52832-QFAA SoC from Nordic Semiconductor.

The nRF52832-QFAA integrates the following elements:

  • A 32-bit Arm Cortex-M4 CPU unit running at 64 MHz, with up to 256/512 kB flash and 64 kB SRAM memory

  • A 2.4GHz RF front-end multiprotocol capable of supporting Bluetooth Low Energy including the high-speed 2 Mbps feature, ANT and 2.4 GHz proprietary protocols

  • A 13.56MHz NFC-A Tag peripheral for use in simplified pairing and payment solutions

  • Wireless connectivity to devices, systems and sensors communicating with low power over long distance.

The Zest_Core_nRF52832-QFAA board features a high density 80-pins interface connector integrating configurable standard communication interfaces (at least 1 SPI, 1 I2C, 4 Analog, 1 UART, 4 PWM, 9 DIO). See 80-pin 6TRON header.
