Bluetooth Transmit Data Module Shanghai Ehong Technologies Inc EH-MA41 User Manual Brand Name:Ehong FCC ID:2ACCRMA41 TX power +5.18dbm, / Bluetooth Transmit Data Module Shanghai Ehong Technologies Inc Description: 3.0 module. It is a highly integrated and sophisticated module which contains all the necessary elements from radio to antenna and a fully implemented protocol stack. It is an ideal solution for integrating Bluetooth® into various products with limited knowledge of Bluetooth® and RF technologies. With AT command stack firmware, designers can easily customize their applications to support different Bluetooth profiles, such as SPP, HID, HFP and etc. And the module can also interface with Apple’s Authentication Coprocessor and build an iAP over Bluetooth application. Typical Bluetooth applications:  Cable replacement  Bar code and RFID scanners  Measurement and monitoring systems  Industrial sensors and controls  Medical devices  Industrial PCs and laptops Features:   -84dBm RX sensitivity  Onboard Meander line PCB antenna support 10 meters  Support sniff and deep sleep mode  Supports master and slave  Supports Bluetooth profiles SPP, iAP, HID  UART and USB and data interfaces  I 2 C Master interface  Support Apple iAP protocol  PCM digital audio interfaces  RoHS compliant Bluetooth V3.0 EH-MA41 is a class 2 Bluetooth® Bluetooth Transmit Data Module Shanghai Ehong Technologies Inc 1.

Power Supply The module accepts a 3.3V DC power input. Power supply should guarantee good ripple suppression and enough current. . 4. Reset The module may be reset from several sources: RESETB pin, power-on reset, a UART break character or via software configured watchdog timer. The RESETB pin is an active low reset and is internally filtered using the internal low frequency clock oscillator. A reset will be performed between 1.5 and 4.0ms following RESETB being active. It is recommended that RESETB be applied for a period greater than 5ms.
