- Metal Shield for interference protection. This is very important because a lot of EMI is coming from our high current fast switching setups in some cases disturbing the correct operation of the module. The main unit is shielded to mitigate that.
- Optional external 2.4GHz antenna. Recommended if you have carbon fiber enclosure or you experience a lot of issues with bluetooth module disconnecting. It makes a noticeable difference. In our tests external antenna doubled the range of operation. But even the default configuration with internal PCB antenna still has much better connection than other bluetooth modules.
- BLE security with Elliptic Curve Cryptography and Man-in-the-Middle protection. All the modules that we use today have bad security or no security at all. It is only a matter of time before someone starts messing around with it. Think about it this way: your board can be hacked, your settings can be messed up, this can result in serious injury. The chance is very low, but why risk? Metr Pro will never bypass communication from an unpaired phone to the VESC. Each Metr Pro module has a random 6 digit PIN code label on the back side which is used for pairing. Once paired, all the communication is encrypted and secure.
- Three bright colored LEDs for easy diagnostics.
