RF-BM-S02A TI CC2541 BLE 4.0 slave module transparent transmission and direct drive module

RF-BM-S02A is a Bluetooth Low Energy (BLE) module based on TI CC2541F256, an 8051 core BLE System-on-Chip (SoC). This PCB module integrates a 32 MHz crystal, a 32.768 kHz crystal, an LC balun, an RF matching filter, and a meander line PCB antenna. It is pre-programmed with the BLE 4.0 stack and an application communication protocol over its full-speed USB interface. The module is highly suited for systems where ultralow power consumption is required. This is specified by various operating modes. Short transition times between operating modes further enable low power consumption. RF-BM-S02A is pin-compatible with the RF-BM-S02 and RF-BM-S02I in the SMT package, if the USB is not used on the RF-BM-S02 & RF-BM-S02I and the I²C/extra I/O is not used on the RF-BM-S02A. Compared to the RF-BM-S02I and RF-BM-S02, the RF-BM-S02A provides lower RF current consumption. The RF-BM-S02A does not have the USB interface of the RF-BM-S02 and RF-BM-S02I, and provides lower maximum output power in TX mode. The RF-BM-S02A also adds a HW I²C interface.
