Development of WIZnet's new chip, the W55RP20, has been completed!
The W55RP20 integrates the W5500, RP2040 microcontroller, and 2MB flash memory into a single SIP (System In Package) solution. This innovative integration allows the powerful libraries and platform of the RP2040 to seamlessly interface with the W5500, offering significant advantages in ease of use and performance.
W55RP-W Board utilizes the W55RP20 chip to combine Pico-W and W5500-EVB-PICO into one cohesive board. This integration enables developers to effortlessly leverage both network communication and wireless functionalities simultaneously.
Key Features of W55RP-W
- Compact Design: By utilizing the W55RP20 chip, which integrates the W5500, RP2040, and 2MB flash memory into a single package, the design is simplified, and space efficiency is significantly enhanced.
- Robust Library Support: The W55RP20 facilitates easy integration of the RP2040’s extensive libraries and platforms with the W5500, enabling the development of diverse and high-performance applications.
- PoE Support: The RJ45 jack on the board supports PoE (Power over Ethernet), allowing for a stable power supply via a connected PoE PD (Power Device) without the need for an additional power source.
Using the BLE_temp_reader example from Pico-W, the wireless functionality was successfully verified.
In this setup, the Pico-W operates as a GATT server that measures temperature and sends data via Notify events upon request from a Central device.
Concurrently, the W55RP-W acts as a GATT client, requesting temperature data from the connected Peripheral device.
The UART0 on the W55RP-W displayed messages confirming the connection to the GATT server and the successful reception of temperature data, demonstrating the effective operation of the system.
Additionally, the WIZnet-PICO-C repository was downloaded to utilize the W55RP20.
By running the TCP server loopback example, the LAN communication capabilities of the W5500 were successfully validated, ensuring reliable network communication functionality.
Future PlansAlthough the W55RP-W board employs the same WiFi-BT combo chip, the cyw43439, as the Pico-W, the pin connections differ. Therefore, modifications are necessary to accommodate the different pin configurations. Comprehensive guides will be provided to facilitate these pin adjustments.
Moving forward, the W55RP-W board will be used to develop a BLE to LAN Gateway project. Upon completion, this project will be uploaded to WIZnet Maker site. This initiative will serve as a practical example for developers, showcasing the versatile applications of the W55RP20 chip in various network and wireless projects.
