Power Supplies
The AS7225 Director Demo Kit is powered by 12V wall plug power adapter. The 12V supply
provides the power to the LDOs as well as MOSFETs and LEDs circuitries. Onboard LDO U1 has
3.3V output, which is used for AS7225, Flash Memory, onboard MCU, and J6 for external sensors.
The 3.3V can be also connected to customer microcontroller through J2. LDO U2 has 5V output
and is connected to J3 for customer development purpose. Each LDO could deliver upto 200mA
total current.
