Raspberry Pi Pico 4$ Microcontroller
Raspberry Pi has developed several microprocessor-based development board which are famous as single board computers.
But, this time Raspberry pi has launched a microcontroller-based development board “Raspberry pi Pico” which uses inhouse designed “RP2040” microcontroller.
The RPi Pico Board
The Pico board is a 51mm X 21mm board with a RP2040 microcontroller on it with 26 multi functional 3.3v GPIO pins.
The board has an onboard LED and a boot select button and a micro USB female port to connect with computer to program and power via USB.
The RP2040 is a new microcontroller developed by Raspberry Pi.
Key Specifications of RP2040
- Dual ARM Cortex-M0+ @ 133MHz
- 264kB on-chip SRAM in six independent banks
- Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
- DMA controller
- Fully-connected AHB crossbar
- Interpolator and integer divider peripherals
- On-chip programmable LDO to generate core voltage
- 2 on-chip PLLs to generate USB and core clocks
- 30 GPIO pins, 4 of which can be used as analogue inputs
- 2 SPI controllers
- ◦ 2 I2C controllers
- 16 PWM channels
- USB 1.1 controller and PHY, with host and device support
- 8 PIO state machines
Like every product RP2040 signifies the specification of the microcontroller.
- “RP” means raspberry pi
- “2” cores
- “0” ARM M0+ architecture
- “4” is floor(log2(ram/16k)) RAM
- “0” is floor(log2(nonvolatile/16k))
Programming the Raspberry Pi pico
Pico supports 2 programming languages “Micro Python” and “C/C++”.
