This product is a 4-button RF remote control, the frequency is 433.92MHz. RF remote control is widely used, such as garage door remote control, electric curtain remote control.
There are four buttons and a red LED on the front of the product. When you press any button, the remote control starts sending signals and lights up LED. On the back of the product there is a screw, Unscrew the screw and install a CR2032 battery as the power source. However his product is shipped without battery, you must purchase the battery yourself. This product uses a PCB antenna, no need to install another antenna.
The communication protocol is proprietary, therefore the product must use with a corresponding RF wireless receiver module (PRODUCT ID: BCM-68F2420-C01) to form a complete transmit / receive function.
The MCU of this product is BC68F2130 from Holtek Semiconductor Inc., it has 2K x16 program memory. We have another RF remote control (Product ID: BCR-68F2123-X01) which uses BC68F2123 MCU. BC68F2123 has 1Kx14 program memory, it probably helps cost control when your design goes to mass production.
This product has an OCDS (On-Chip-Debug-Support) interface, you can use this interface to connect Holtek's e-Link simulator or e-WriterPro writer to burn MCU program to the MCU on the RF remote control. However, we recommend that you be properly trained and familiar with the products to suit this operation.
