4.2 Power supply
There are various options for easily powering the MM2040EV PICO Adapter board from a 5V USB
supply through a Micro-B USB connector or 5V DC supply input from 2-pin JST connector CN10, or
the 5V supply from BRT EVE module through the respective connectors, J1 or CN15.
Note: Users should check the maximum current provided by their chosen power source to ensure it
can supply sufficient current for the overall consumption of their EVE module and peripherals.
This 5V supply is the main power supply for the system and will be fed to the RT6150 buck-boost
Switched-Mode Power Supply (SMPS) IC which is on board of PICO module to generate a fixed 3.3V
output for the RP2040 IC and those peripheral’s 3.3V supply.
4.3 Raspberry Pi PICO module and its MCU
Raspberry Pi PICO module is designed based on Raspberry Pi RP2040 micro-controller unit (MCU)
with the following key features:
•
•
RP2040 microcontroller with 16M-bit (2M-byte) Flash
Micro-B USB port for power, data and for reprogramming the Flash; reprogramming the Flash
can be done by simply dragging and dropping a file onto the Pico which appears as a mass
storage device.
26 multi-function 3.3V General Purpose I/O (GPIO) with 23 GPIOs being digital-only and 3
ADC capable GPIOs.
3-pin ARM Serial Wire Debug (SWD) port; the standard Serial Wire Debug (SWD) port can
reset the system and load and run code without any button presses as well as for debugging
purpose.
For full details of the Raspberry Pi PICO module, please see the Raspberry Pi Pico datasheet while for
full details of RP2040 microcontroller, please see the RP2040 Datasheet.
