BLE 5.1, 802.15.4 Modules BM833A/AF, BM833/F/E Ver 0.90 Nov. 2019 BluNor BM833/A are powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using TM Nordic nRF52 SoC. With an ARM Cortex M4(F) MCU, up to 512KB flash, 128KB RAM, embedded 2.4GHz multi-protocol transceiver, and an integrated PCB trace antenna or an u.FL for external antenna. It allows faster time to market with reduced development cost. BM833A/AF are designed to minimize PCB cost and to maximize efficiency in production line dedicated for Bluetooth modules. The cost of using BM833A module can be lower than designing-in SoC at any quantity. At low cost, BM833A are full feature modules. Inductors for DCDC converter are integrated. All 32 GPIOs are accessible. BM833/F/E, nRF52833 modules have compatible footprint for upgrading. They offer more GPIOs, more memories, +8 dBm TX. Array antenna will be supported in BT833 Series modules. BM833A Specications: Nordic nRF52 with ARM Cortex M4 at 64 MHz. 20 channel CPU independent Programmable Supported data rate: Peripheral Interconnect (PPI).
