Raspberry Pi has launched its first microcontroller-class product: Raspberry Pi Pico. The new board, which is priced at US $4, is built on the brand-new RP2040 chip developed by Raspberry Pi.
According to the announcement, the fully open source RP2040 is the result of years of hard work by the Raspberry Pi in-house chip team, which had three main design goals in mind: “high performance, particularly for integer workloads; flexible I/O, to allow us to talk to almost any external device; and of course, low cost, to eliminate barriers to entry.”
The result is “an incredibly powerful little chip,” that includes the following features (among others):
- Dual-core Arm Cortex-M0+ @ 133MHz
- 264KB of on-chip RAM
- Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
- 30 GPIO pins, 4 of which can be used as analogue input
- USB 1.1 controller and PHY, with host and device support
