Specifications

The connector on this product is 200-FH-1-12-43-S-28-24-GO-A (socket), and the square pin type header pin

(product example: IK210SM-S12G-T15) is suitable as the parent device side connector.

・

Power supply (1 pin)

Input power supply voltage DC3.0V～3.6V, current consumption 0.09A maximum

・

Trigger signal (3-pin)

Active low (minimum 100uS width) transmission request signal.

It sends a “TRIGGER” signal based on the preselected radio system specifications.

・

Internal operation status signal (4,5)

This is a 3V-CMOS logic signal that indicates the operating status of wireless transmission.

TX_COMPLETE/READY becomes Low when the trigger signal is recognized, and becomes High

when the transmission operation is completed.

・

UART interface (7,8 pin)

3V CMOS level UART interface signal. It can be directly connected to the MPU of the parent device.

Serial communication parameters Communication speed 38400bps, 8bit, No parity, Stop 1 bit

Do not connect RS232 level signals as this will damage the internal circuitry.

Use a level converter circuit when connecting a personal computer, etc.

・

Reset signal (9 pin)

This is an active low hardware reset signal (minimum 1000uS width) that resets the internal

operation of the transmitting radio wave module from the parent device.

・

ANTTENA signal (11 pin)

Active low Testing enable signal.
