Raspberry Pi Pico/2, Pico mit WLAN-Entwicklungsboard, Pico oder Pico H mit Pin-Header, Unterstützt MicroPython/C++

Raspberry Pi Pico is mainly divided into the following versions: Original Raspberry Pi Pico: This was the initially launched version, priced at around $4. It is a low-cost, high-performance microcontroller development board. It is equipped with the RP2040 dual-core Cortex-M0+ microcontroller developed by Raspberry Pi itself, with a frequency of 133 MHz. It has 264 KB of SRAM and 2 MB of on-board flash memory. This version does not have built-in WiFi or Bluetooth functionality, but these functions can be added through external modules. It provides 26 GPIO pins, among which 3 can be used as analog inputs. It also has 2 UARTs, 2 SPI controllers, 2 I²C controllers, 16 PWM channels and other rich peripheral interfaces. Raspberry Pi Pico H: It is basically the same as the original version in terms of functionality. The main difference is that it has pre-soldered pins, which makes it convenient to connect with external devices and components, making it more suitable for beginners and amateur enthusiasts. In addition, it is also equipped with a 3-pin JST debugging connector, which is convenient for advanced users to find and fix errors when running code. Raspberry Pi Pico W: Based on the original version, it adds built-in WiFi functionality (supporting 802.11b/g/n WiFi 4), and it is possible to support Bluetooth functionality through firmware updates in the future. This version is suitable for projects that require wireless connection functionality, such as Internet of Things devices, wearable devices, and remote sensors. Raspberry Pi Pico WH: It is a variant of Pico W, with pre-installed pins, which makes it convenient to connect with external devices and components, allowing beginners to get started quickly. Raspberry Pi Pico 2: It was launched in August 2024, equipped with the RP2350 microcontroller chip. This chip adopts dual-core Arm Cortex-M33 and dual-core RISC-V Hazard3, with 520 KB of SRAM and 4 MB of flash memory. Compared with the original Pico, it has more po
