Description :
This is the Raspberry Pi Pico W, the newest board from the Raspberry Pi Pico series. The W stands for Wireless, so it offers a 2,4GHz wireless internet (WiFi) connection.Like the standard Pico, the Pico W is a microcontroller board that is based on the RP2040 chip. You get 2MB flash memory which can be programmed via the built-in micro USB port. The Pico can also be powered via this micro USB port.On the board are 40 pin connection. Here you can solder Pin headers so that you can connect the Pico W to a Breadboard can place. You can also build it directly into a project.There are 26 multifunctional GPIO pins available. Of these, 23 are exclusively for digital use. 3 are ADC capable.As with the first Pico, there is a 3 pin ARM SWD (debug) port. This has been moved to the center of the board.The RP2040 chip contains a Dual-core cortex M0+ operating at 133MHz and 264kByte SRAM.The Pico W can be programmed in C & Micro Python. This board is great fun for beginners, but also for advanced users.
