Headers & WiFi
Raspberry Pi has launched two new products. The Raspberry Pi Pico H and the Raspberry Pi Pico W. The Pico H comes with pre-soldered pin headers. This allows you to easily place the Pico on a Breadboard place. For easy debugging there is a 3-pin JST 'SH' Connector at the upper side.
The Pico W comes with WiFi 4 support. It works with Infineon CYW43439 chips for Single-band 2,4GHz wireless interfaces (802.11n).
Pico H specifications
De Raspberry Pi Pico has the same specifications as the original Pico.
- RP2040 Microcontroller chip designed by Raspberry Pi
- Dual-core arm cortex m0+ processor, flexible clock works up to 133MHz
- 264KB SRAM and 2MB on-board flash memory
- USB 1.1 with device and host support
- Low-power sleep mode
- Drag-and-drop programming via USB
- 26 × multipurpose GPIO pins
- 2×SPI
- 2×I2C
- 2×UART
- 3 × 12 bit ADC
- 16 × Adjustable PWM Channels
- On-chip clock and timer
- Temperature sensor
- On chip accelerated floating point libraries
- 8 × Programmable I/O (PIO) state machines
The standard Pico does not have Pin headers and a debug connector. The Pico H does have these.
Pico W specifications
De Raspberry Pi has the same specifications as the Pico. However, this version does offer a unique extra. Namely WiFi 4. It contains an Infineon CYW4343 chip. It offers single-band 2,4 GHz wireless interfaces (802.11n).
- Wireless (802.11n) Single band (2,4 GHz)
- WPA3
- Soft Access Point supports up to 4 clients
The wireless interface is connected to the RP2040 microcontroller via SPI. Due to pin restrictions, some wireless interface pins are shared. THE CLK is shared with the VSYS pin. The VSYS pin can therefore only be read when no SPI transaction is in progress.
For optimal use, the antenna must be free. Placing metal close to the antenna may cause performance degradation.
Adding grounded metal to the sides of the antenna can improve the bandwidth of the antenna.
