Pololu RC Switch with Digital Output

Pololu RC Switch with Digital Output

This tiny board converts hobbies radio control pulses to digital on / off RC switch and simple RC adapter applications. One output indicates the presence of a valid RC signal (10-100 Hz pulse rate, 0.5-2.5 ms pulse width), and the pulse rate is above or below the 1.6 ms threshold (with ± 0.1 ms hysteresis) .

overview

The Pololu RC switch with digital output can be used with standard hobby radio control systems. Example applications include converting extra RC receiver or servo controllers can not control the LEDs or RCs. MOSFETs or relays and connecting RC systems to microcontroller. Two or more of the signal is on or off. This compact unit measures a mere 0.4 "x 0.4" and weighs just 0.3 g (0.01 oz).

Using the RC Switch

Connections

The RC switch PCB has two connections, one on each side. The remote control is connected to the RC receiver or servo controller; the side with four pins has the power supply and connections. The RC signal input, the voltage can range from 0 to 7 volts, and the threshold for a logic high is approximately 1 V. The VCC pin can be connected to the RC supply, VRC, by either the RC device or the RC receiver. if the connection between the two power pins is not made, VRC can be left disconnected from the RC switch board.

Outputs and Indicator LED

The board has two steps, 20 mA each of which is capable of sourcing or sinking. The primary output, OUT, goes high (on) when the current signal is 1.6 ms. There is approximately ± 0.1 ms of hysteresis on the threshold, meaning that the pulse width will have to be approximately 1.5 ms before the output is 1.5 ms to turn off. A secondary output, GOOD, can be used to indicate the RC signal (10-100 Hz pulse rate, 0.5-2.5 ms pulse width).

An LED on the RC switch indicates the status of the RC signal (and outputs). When a valid RC signal is not detected (GOOD and OUT both low), the LED flashes with a duty cycle of approximately 50% (ie the LED is on for as long as it is off). When a valid signal is detected (GOOD high and OUT low), the LED flashes at a very low duty cycle (ie very short flashes). When a good signal is detected, the LED turns on (no flashing).

Included Hardware

A 7-pin 0.1 "straight breakaway male header is included with the Pololu RC switch with digital output, which can be used to connect the RC switch to perfboards or breadboards.
