UC5550
Overview
Our UC5550 module is a step up from the UC2550 in terms of processor speed, internal flash, external RAM and available peripherals. Unlike the UC2550, the UC5550 has USB host, parallel LCD, DCMI interfaces and Ethernet PHY support.
We currently stock the UC5550 both with and without Wi-Fi depending on the model. The current models are shipping with 32 MByte of external RAM and 4 MByte of external flash. We also offer customized, non-stock versions of our SoMs. See Options below for more information.
Getting Started
The UCM development options can greatly simplify the process of building a product or prototype using the UC5550. Options include a development board and displays which can get you programming in minutes. Please refer to the Development Options page for more information.
Using TinyCLR OS
TinyCLR provides a way to program the UC5550 in C# or Visual Basic from the Microsoft Visual Studio integrated development environment. To get started you must first install the bootloader and firmware on the UC5550 (instructions below) and then go to the TinyCLR Getting Started page for instructions on setting up the host computer and writing and deploying programs.
Loading Bootloader Version 2
Download the UC5550 bootloader here.
Go to the Uploading DFU Files section of the STM32 Bootloader page for instructions on installing the bootloader.
Loading the Firmware
Tip
First make sure you have bootloader v2 loaded. This needs to be done only once.
To activate bootloader v2, hold the LDR0 signal low (press BOOT B on UCM Dev and Breakout boards) while resetting the board.
Download the UC5550 firmware and follow Loading the Firmware steps.
Setup the Host Computer and Start Coding
Now that you have installed the bootloader and firmware on the UC5550, you can setup your host computer and start programming. Go to the TinyCLR Getting Started page for instructions.
