🍓 Raspberry Pi Pico W – A $6 board with WiFi 4

Fast cores, large memory, and flexible interfacing make RP2040 a natural building block for Internet of Things (IoT) applications. But Pico itself has one obvious missing feature for IoT: a method for connecting to the network. Now, this is about to change.

Raspberry Pi Pico W is priced at $6, and brings 802.11n wireless networking to the Pico platform, while retaining complete pin compatibility with its older sibling.

Like the original Raspberry Pi Pic, the new board supports both C programming and MicroPython, but the Raspberry Pi Pico W comes preloaded with MicroPython. Programming is about the same, except for the additional Wi-Fi API.

📃 Raspberry Pi Pico Variants – A Detailed Comparison

Raspberry Pi Pico is a low-cost, versatile microcontroller development board from the Raspberry pi foundation. Let’s look at all these variants and their differences.

▫️ Raspberry Pi Pico is the first low-cost Microcontroller development board from the infamous Raspberry Pi Foundation.

▫️ Pico H is the same as the original Raspberry Pi Pico. There are no functional differences between them. The main difference is that the old gold-plated castellated holes are removed, and the header pins are pre-soldered. Another major difference is the new debug connector. The original Pico has a 2.54mm standard header pi for the debug.

▫️ Even though the Raspberry Pi Pico is a very powerful board, its main disadvantage over its competitors like ESP8266 or ESP32 is the lack of wireless connectivity. The new Pico W and WH have the solution for that. The new Pico W comes with a new chip supports both 2.4 GHz WiFi 4 and Bluetooth LE 5.2.
