Fanstel’s BC832 micro BLE 5.0 module for wearable IoTs is an NFC module with a Nordic nRF52832 SoC and incorporates an integrated chip antenna. The SoC is an ARM Cortex M4F processor with 512kB of flash memory and 64kb of RAM. Measuring 7.8mm x 8.8mm x 1.3mm, it has 16 castellated pins for applications needing a limited number of GPIOs. An additional 20 land grid array (LGA) pins provide access to all nRF52832 GPIO pins. This device’s features include 128-bit AES HW encryption with EasyDMA, up to 32 GPIOs, a temperature sensor, a 12-bit/200kSps ADC (8 configurable channels with programmable gain), and a type 2 NFC-A tag interface for out-of-band pairing.
