Product COM-09638 | about a year ago

Purchased and verified that Digikey Part Number A100192-ND “Cable Assembly MINI CT 2POS” properly connects to the contact carrier.

I think that the cable assembly is available from digikey (part #A100192-ND). i haven’t purchased one yet, but the drawing looks spot on. Should solve your connectivity problems.

I have some serious bones to pick with this Dev board. The biggest snafu is that the HR (Heart Rate) pin from the RMCM01 (Polar receiver) is not broken out anywhere on the board! Duh, this is why I bought the board. Second, why is the PIC16F913 code protected? Anyone who buys this board to experiment with, might want to reflash it to stock form.
The students in my Embedded class have to totally jury-rig the board to make it work on their project. totally uncalled for on a development board.
That said, the RMCM01 works well with every heart rate strap that I own. The firmware on the PIC works well and is reasonably well documented.

The pin-out is just fine, use your DMM in diode mode to identify pin 1. The color intensity varies noticeably between the blue LEDs. Timing constraints with a typical MCU will limit you to about 512 colors. Wish the price was more modest.

Duplicating my post… These modules work just fine. Just remember that the receivers have automatic gain control and will increase their gain in order to find a signal. This means that the receiver will start to generate noisy output unless you transmit something about every 10mS. I dropped the antenna from my transmitter and signal integrity on the receiver improved – I left the antenna on my receiver. Further suggestions, put some filter caps across the power supply pins and integrate a preamble byte and a checksum. Have the receiver search for the preamble and verify the packet with the checksum.
