Waveshare RP2040-Zero High-Performance Pico-Like MCU Board

The RP2040 microcontroller chip, designed by Raspberry Pi in the United Kingdom, features a dual-core Arm Cortex M0+ processor with a flexible clock running up to 133 MHz. It boasts 264KB of SRAM and 2MB of on-board Flash memory, as well as a USB-C connector that keeps the device up-to-date and easier to use. The castellated module allows for direct soldering to carrier boards, and the chip supports USB 1.1 with both device and host capabilities. Low-power sleep and dormant modes are also available.

This microcontroller enables drag-and-drop programming using mass storage over USB, and it provides 29 multi-function GPIO pins, 20 of which are accessible via the edge pinout, with the remaining 9 available through solder points. The RP2040 chip offers 2 SPI, 2 I2C, and 2 UART interfaces, as well as 4 12-bit ADCs and 16 controllable PWM channels. An accurate on-chip clock and timer, along with a temperature sensor and accelerated floating-point libraries, are also included. Additionally, the device features 8 programmable I/O (PIO) state machines for custom peripheral support.

Waveshare, a company founded in 2006 and headquartered in Shenzhen, China, with additional offices in Hong Kong, offers a wide range of products, including the RP2040-based development boards. These boards come in various configurations, such as the Original with case, Mini, LCD, Plus, and Mini-2 versions.

The boards share several common features, such as the Raspberry Pi official RP2040 microcontroller, USB-C connectivity, and 2MB of Flash memory. However, they differ in their power regulation, with some using a DC-DC converter (up to 1800mA) and others employing an LDO (up to 800mA). Additionally, some models include a battery header for concurrent recharging and powering, as well as an integrated 0.96-inch IPS LCD display.

Waveshare's product range extends beyond microcontrollers, covering areas such as displays, sensors, wireless communication, and more. Their products are certified by various authorities, including CE, FCC, and RoHS, ensuring compliance with relevant standards.

In addition to their development boards, Waveshare offers a wide range of other products, including LCD screens, touch screens, OLED displays, cameras, and other components in various sizes. The company's focus on innovation and support for its customers has enabled it to grow alongside the demand for advanced display and IoT technologies over the past decade.
