3.3 Processor

The processor is based upon the new Raspberry Pi RP2040 silicon (U1). This microcontroller provides opportunities

for low-power Internet of Things (IoT) development and embedded machine learning. Two symmetric Arm®

Cortex®-M0+ clocked at 133MHz provide computation power for embedded machine learning and parallel

processing with low power consumption. Six independent banks of 264 KB SRAM and 2MB are provided. Direct

memory access provides fast interconnect between the processors and the memory that can be made inactive

along with the core to enter a sleep state. Serial wire debug (SWD) is available from boot via the pads under the

board. The RP2040 runs at 3.3V and has an internal voltage regulator providing 1.1V.

The RP2040 controls the peripherals and digital pins, as well as analog pins (A0-A3). The I2C connections on pins A4

(SDA) and A5 (SCL) are used for connecting to the onboard peripherals and are pulled up with a 4.7 kΩ resistor.

SWD Clock line (SWCLK) and reset are also pulled up with a 4.7 kΩ resistor. An external MEMS oscillator (U7)

running at 12 MHz provides the clock pulse. Programmable IO helps to the implementation of arbitrary

communication protocol with minimal burden on the main processing cores. A USB 1.1 device interface is

implemented on the RP2040 for uploading code.
