This product is used to facilitate the use of our OOK transmitter module. You can save time for making peripheral circuits by inserting a transmitter module into the slot of the evaluation board to start using the keypad, LED, battery slot, etc.

This product must be used with the OOK transmitter module we sell, including Parallel OOK Transmitter module 433MHz (BCM--68F2123-X02 and BCM-68F2130-X02)、Serial OOK Transmitter module 433MHz (BCM-2102-X03). Either of the three transmitter modules can be plugged into the slot of this product.

This evaluation board has four buttons, two LEDs, and the 12-pin slot used to connect the transmitter module. There is a battery slot on the board. This product is shipped without a battery. You must load a CR2032 lithium battery.

This product has a 6-pin pin stick which is the 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 transmitter module. However, we recommend that you be properly trained and familiar with the product to suit this operation.
