Hardware Assembly

USB Programming

The USB connection is utilized for configuration and serial communication. Users only need to connect their DAN-F10N Dualband L1/L5 GNSS breakout board to a computer using a USB-C cable.

The DAN-F10N Dualband L1/L5 GNSS breakout board with a USB-C cable attached.

USB Driver

Users will need to install a USB driver before they can interact with the GNSS module. For more details, please refer to the USB Driver section of the Software page.

Default Settings

  • Baudrate: 38400bps
  • Data Bits: 8
  • Parity: No
  • Stop Bits: 1

External Antenna

GNSS antenna connection

Soldering the EXT_ANT jumper on the DAN-F10N GNSS breakout board to utilize the GNSS antenna attached to the U.FL connector.

In order to receive GNSS signals, a compatible antenna is required. Users have the option of utilizing the integrated L1/L5 dual-band patch antenna or an external GNSS antenna. An external antenna can be connected to the U.FL connector on the board with an U.FL to SMA adapter cable. In order to trigger the RF switch inside the DAN-F10N GNSS module to utilize the U.FL connector as its signal source, the EXT_ANT jumper must be modified.

Tip

For the best performance, we recommend users choose a compatible L1/L5 GNSS antenna and utilize a low-loss cable. Also, don't forget that GNSS signals are fairly weak and can't penetrate buildings or dense vegetation. The GNSS antenna should have an unobstructed view of the sky.

Breakout Pins

The PTH pins on the DAN-F10N Dualband L1/L5 GNSS breakout board are broken out into 0.1"-spaced pins on the outer edges of the board.

BlueSMiRF Header Pins

One of the two sets of PTH pins on the DAN-F10N Dualband L1/L5 GNSS breakout board is labeled BlueSMiRF. This set of header pins breaks out the UART interface of the DAN-F10N module, which can be connected to a microcontroller or RF transceiver; such as the BlueSMiRF v2, Bluetooth® serial link. The BlueSMiRF v2 comes in two variations, with PTH pins or male header pins. Users can directly solder the PTH variant to the board with male headers, for a more permanent installation; otherwise, for more flexibility, a stackable header can be utilized.

Bus Contention

To avoid bus contention issues with the USB-C connection, users may want to use the RXD and TXD jumpers to disconnect the CH340 USB-to-serial converter from the UART interface of the DAN-F10N GNSS module.

When connecting the DAN-F10N Dualband L1/L5 GNSS breakout board to another device, users need to be aware of the pin connections and voltage ranges of the products. Below, is a table of the pin connections that users can reference.
