5.1 Connecting Modules
The Koala EVM features a 100 pin COM8 socket for connecting Wi-Fi / Bluetooth modules. The connector is
marked “COM8” and is notched. Position of the notch must be observed to avoid damaging the module.
Figure 7: COM8 connector. The notch is located on the bottom-right corner of the connector.
Clarinox WMI modules may also be connected to the Koala EVM with the dedicated WMI connectors. The WMI
module is to be inserted in both connectors, observing the notches for correct placement of the module.
