Earlier this year, Raspberry introduced the Raspberry Pi Pico microcontroller, which costs just $ 4. One of the secrets of such a low price lay in the company’s own RP2040 chip.
This chip is now available for purchase separately for just $ 1. Its configuration and capabilities have not changed. It’s all about the same two Cortex-M0 + cores with a frequency of 133 MHz, 264 KB of its own memory, as well as a number of controllers. In addition, the solution supports up to 16MB of external flash memory via the QSPI bus.
Of course, without a board, the chip is conditionally useless, but the ability to buy it separately will simplify the work of some developers and enthusiasts who would like to try out the RP2040, but the Raspberry Pi Pico microcontroller itself for some reason does not suit them.
