Wireless Transmission Module with UART Interface and Spring Antenna
Wireless Transmission Module with UART Interface and Spring Antenna
Wireless Module is a high-performance, long-range transceiver based on the Semtech SX1278 LoRa chip, designed for ultra-long-distance, low-power, and low-data-rate wireless communication. Operating in the 433MHz ISM band, this module uses LoRa (Long Range) spread spectrum technology, enabling communication over distances of up to 10 km in open areas with minimal power consumption.
Equipped with a UART serial interface, the RA-01 is ideal for microcontroller-based systems such as Arduino, ESP32, STM32, and other embedded platforms. The included spring antenna enhances signal reception while maintaining a compact form factor suitable for space-constrained projects.
Key Features:
LoRa Modulation Technology: Offers long-range communication with strong anti-interference and high sensitivity
Frequency: 433 MHz ISM band
Transceiver IC: Semtech SX1278
Communication Interface: UART (TTL level), easy to connect with most microcontrollers
Range: Up to 10 km (line of sight, with proper antennas and low interference)
Data Rate: Programmable, supports low-data-rate transmission (up to 300 kbps)
Power Supply: 3.3V operation (ensure regulated power for stability)
Antenna: Compact spring antenna included for improved signal performance
Compact Design: Ideal for integration in portable or embedded wireless systems

How to Request a PCB Layout / Design
- Send your complete schematic or diagram via our Facebook page.
- Our team will review your diagram carefully to understand the design scope and requirements.
- A detailed quotation will be provided based on:
-
- Design complexity
- Board size and number of layers
- Components and package types
- Special routing or manufacturing requirements
📌 Providing your diagram is essential so we can give you an accurate and fair quotation.
PCB Layout & Design Requirements
To ensure quality and accuracy, please note the following:
- All schematics must be clear, complete, and properly labeled
- Specify:
- Board dimensions (if available)
- Number of PCB layers
- Preferred components or footprints (if any)
- Hand-drawn, unclear, or incomplete schematics are not accepted
- Rush or urgent requests may incur additional charges
What’s Included in the Design Package
Each completed project includes the following deliverables:
✅ 2D PCB layout images
✅ 3D PCB render images
✅ PCB Gerber files (ready for fabrication)
✅ Bill of Materials (BOM)
✅ Component Placement List (CPL / Pick-and-Place file)
