Colibri Carrier Board Design Guide are intent to be used with the carrier board. Currently, the Colibri T30 is the module with the highest current consumption. This module can draw up to 1.2A. In order to leave enough margins, take 2A into the power budget for the Colibri T30 module. Do not forget taking the additional current consumption of the peripheral devices on the 3.3V rail into the budget.
Colibri module is critical, if done wrong the Colibri can be damaged due mechanical stress!
