BUY Sipeed Tang Mega 138K Dock: A Powerful and Affordable FPGA Development Platform

The Sipeed Tang Mega 138K Dock is a compact and versatile FPGA development platform designed to cater to a wide range of projects. It boasts a potent combination of high performance and cost-effectiveness, making it an attractive choice for developers, hobbyists, and makers alike.

At the heart of the Tang Mega 138K lies the GOWIN GW5AST RISC-V FPGA, a powerful chip with 138,240 logic units, a multitude of registers, and 12 phase-locked loops, providing ample resources for complex designs. The platform's development board is packed with essential features, including a PCIe x4 interface, a Gigabit Ethernet port, and a wealth of I/O options.

A Powerful Core:

The Tang Mega 138K SoM (System on Module) features a built-in RISC-V processor clocked at 800MHz, along with 4Gbit DDR3 x2 for memory, 128Mbit flash storage, and advanced BTB connectors. This powerful core is further augmented by components like DC-DC converters, a DDR power IC, and user-configurable keys, ensuring efficient operation and user control.

Versatile Connectivity:

The Tang Mega 138K Dock board is well-equipped with high-speed and versatile interfaces, including Gigabit Ethernet and USB 3.0 for fast communication. It also boasts a range of connectors for diverse applications, including DVI in/out for video, stereo audio, a MIC array for voice input, and MIPI DPI RGB LCD for display connectivity.

High-Speed Performance:

The board is fully compatible with PCIe 2.0, featuring an external x4 interface with transfer rates up to 20GT/s for high-bandwidth data transfers. Additionally, a USB3 interface powered by the WCH CH569W supports USB-C cables with transmission rates up to 5Gbps, enabling high-speed communication.

Comprehensive Features:

The Tang Mega 138K Dock board is designed to be a comprehensive development platform. Beyond its core functionalities, it includes power management with a 12V DC input, battery connection, and charge/discharge management PMU. It also features a microSD slot for additional storage, gamepad connectors for gaming applications, and multiple user-configurable keys for custom functionality.

Cost-Effective Options:

Sipeed offers two versions of the Tang Mega 138K: The standard version, available for $69, and the Pro version, priced at $119. While both versions offer the same core functionality, the Pro version boasts a PCIe 3.0 x8 interface for increased bandwidth, while the standard version utilizes a PCIe 2.0 x4 interface, offering excellent value for users requiring high cost performance and limited volume. The Pro version is ideally suited for high-speed interface development scenarios, while the standard version is an excellent choice for applications that prioritize cost and functionality.
