uUSB-PA5-II
Overview and Connectivity
Overview and Connectivity
The microUSB Programming Adaptor uUSB-PA5-II is a USB to Serial-TTL UART bridge converter which is simple, cost-effective, tiny and easy to use. It uses a mini-B type USB connector to connect to your PC. The uUSB-PA5-II is based on the SiLabs CP2104 USB to UART Bridge IC from Silicon Labs. It provides the user with multi-baud rate serial data up to 3M baud rate, and access to additional signals such as flow control in a convenient 10-pin 2.54mm (0.1″) pitch Dual-In-Line package.
The main 5-pin interface is a standard 2.54mm (0.1″) pitch female header, designed to connect directly to a majority of the 4D Systems modules. RX and TX signals are both 3.3V and 5V tolerant. The uUSB-PA5-II is ideal for prototype or production.
Features and Benefits
Features:
- USB 2.0 compliant, full speed, 12 Mbps maximum speed. Suspend is supported.
- Hardware or Xon/Xoff handshaking is supported, with speeds ranging from 300bps to 2Mbps.
- UART supports 5, 6, 7, or 8 data bits, 1, 1.5, or 2 stop bits, and odd, even, mark, space, and no parity.
- Power on reset circuit
- Virtual COM port drivers allow operation with existing COM port PC applications.
- USB powered
- Traffic/Operation LED indicates board status
- Additional flow control and features are available for the user to solder, using standard 2.54mm (0.1″) pitch through holes along each side of the PCB.

Frequently Asked Questions
Find quick answers about our display modules, embedded integration, customization capabilities, and system compatibility.
How do I choose the right display module for my project?
Start by identifying the demands of your product environment: required screen size, touch capability, operating conditions and UI complexity. Our consistent form-factor families allow you to select a module that fits your constraints today and upgrade performance later without redesigning your enclosure or PCB. Our documentation hub provides comparison tables to assist selection.
What is the difference between a smart display and a host-driven display?
Smart displays include an onboard processor that handles graphics, widgets, UI logic and drawing commands internally. This reduces load on your host MCU, simplifies code and often shortens development time dramatically. Host-driven modules require the host MCU to manage everything, which may be appropriate for minimal UIs but introduces more integration work.
Can I upgrade processors without changing my enclosure or PCB?
Yes. Our architecture is deliberately designed around footprint consistency. Most display families maintain identical mechanical and electrical footprints across multiple processor types, enabling generation-to-generation performance improvements without mechanical redesign.
Do you offer non-touch and touch options?
Yes. Many display families provide variants for non-touch, resistive-touch and capacitive-touch configurations. Capacitive-touch variants are recommended for modern, responsive UI experiences.
