In a nutshell: The new Raspberry Pi Pico W provides built-in Wi-Fi connectivity to the corporate’s common Pico board launched final yr. These wireless-enabled boards shall be an awesome match for a lot of third-party merchandise, comparable to IoT gadgets. Meanwhile, the Pico H and Pico WH add pre-populated headers and a 3-pin debug connector.
The Raspberry Pi Foundation has simply introduced three new variants of its tiny Pico board. The Raspberry Pi Pico W provides built-in Wi-Fi connectivity, whereas the Pico H and Pico WH are variations with pre-installed header pins and a three-pin debug connector.
The authentic Raspberry Pi Pico launched early final yr for simply $4. It comes with an RP2040 chip constructed on TSMC’s 40nm course of and options two Arm Cortex-M0+ cores clocked at 133 MHz and 264KB of on-chip RAM. The board additionally has 2 MB of flash reminiscence and a micro USB 1.1 port.
As beforehand talked about, the brand new Pico W will get Wi-Fi capabilities by an Infineon CYW43439 wi-fi chip with an onboard antenna. It’s a 1×1 SISO answer with help for the two.4 GHz-only Wi-Fi 4 (802.11n) protocol and 20 MHz-wide channels, permitting for a PHY information fee as much as 96 Mbps. Interestingly, this chipset additionally options built-in Bluetooth 5.2 help, however the firm hasn’t enabled it on the Pico W at launch.
These new Wi-Fi variations will possible be highly regarded for IoT purposes, with the corporate claiming it bought practically 2 million items of the usual Pico board prior to now 18 months.
The Pico H and Pico W are already out there for $5 and $6, respectively, whereas the Pico WH will launch subsequent month for $7.
