BytePipe x9002
HDK Quick Start Guide
OVERVIEW
The BytePipe SDR Development Kit consists of a Hardware
Development Kit (HDK) main board combined with a Software
Defined Radio (SDR) System on a Module (SOM) and supporting
cables, power supply, and software to enable testing and
development with the NextGen RF BytePipe SOM.
The SOM Development Kit can be used as an evaluation tool and
prototyping platform to aid in integration of the SOM into a full-
scale product, or as a starting point to explore custom
development of an SDR transceiver.

Kit Contents
The HDK can be purchased with or without a SOM. If purchased with a SOM, the kit will arrive with the SOM
preinstalled and is ready to be used right out of the box. If purchased separately, the SOM will need to be
properly installed on the HDK prior to use.

SOM Mounting Hardware
The HDK/SOM combo kit includes spacers and screws securing the SOM on the HDK. These are to ensure the
SOM does not become disengaged from the HDK and damaged during shipping. This hardware is not required
for operation and can be left in place or discarded.

ESD Warning
Observe precautions for handling electrostatic sensitive devices.
SOM Heatsink and Fan
If the SOM was purchased with the HDK, it will come with a pre-installed heatsink and fan. If purchased
separately, the heatsink and fan need to be installed by following the steps below.
CAUTION: Do not operate the SOM without adequate thermal dissipation as damage can occur.
1. Remove any labels from the gold colored shield of the SOM and ensure the surface is clean.
2. Remove the blue plastic from the bottom of the heatsink to expose the adhesive thermal tape.
3. Align the heatsink on the SOM shield such that it is centered in both directions and the fan wire faces
the direction shown below.
Figure 5: SOM Heatsink and Fan Installation
4. Press the heatsink and shield together firmly for a few seconds to ensure proper adhesion.

DOC-1017 Rev. A1 Page | 8
SOM Installation
The HDK/SOM interconnect has two board-to-board connectors and six RF connectors. Care must be taken to
ensure they are properly aligned before applying the force necessary to fully engage the connections.
If using the U.FL connectors on the SOM, do not install the SMPM adapters –skip to step 3.
1. Inspect the SMPM adapters to ensure they are not damaged.
2. Install the SMPM adapters in each of the six SMPM connectors of the HDK by aligning them vertically
and pressing down.
Note: If tools are used to install the adapters, use extreme caution as the adapters can be easily
damaged.

3. Place the SOM on the HDK so that the six RF connectors and two board-to-board connectors are aligned.
Figure 7: SOM Installation on HDK
4. Press the SOM firmly until all connections are fully seated.
5. Plug in the fan power connector to J1 of the HDK. This connector is keyed to ensure the proper polarity
to the included fan. If using a different fan, ensure the pinout matches using the detail below.

HDK Setup
The HDK comes with a micro-SD card containing a recent version of RFLAN, a power supply, and a USB cable for
serial communication. To get started using the HDK, follow the steps below.
1. Ensure the HDK power switch is in the “OFF” position.
Figure 10: Power Switch - OFF
2. The HDK comes with a micro-SD card containing a recent version of RFLAN, but it is recommended that
this be checked to ensure it is the latest release. The latest software can be found on the NextGen RF
Design GitHub here:
https://github.com/NextGenRF-Design-Inc/bytepipe_sdk/releases
Detailed instructions on preparing the micro-SD card can be found here:
https://github.com/NextGenRF-Design-Inc/bytepipe_sdk/blob/main/docs/sd_card/README.md
Be sure to download the software version that matches the SOM logic size and processing system (BP-
2CG or BP-3CG) or the SOM will not boot.
3. Ensure the micro-SD card is installed in the micro-SD card holder and that the holder is closed in the
“LOCK” position. The holder is a flip-type, so it is opened by sliding the metal cover out, then lifting up.
The micro-SD card slides into the open metal cover. The holder is closed by setting it down and sliding
the metal cover and micro-SD card back in.

4. Connect desired RF test equipment to SMA connectors (or directly to the U.FL connectors if not using
the SMPM adapters).
Figure 12: RF Test Equipment Connections
5. Connect a micro-B USB 2.0 cable between the JTAG/USB port of the HDK and a PC or laptop.
Figure 13: Serial Connection
6. Plug in the AC/DC power supply included in the kit, and plug the barrel jack into the HDK.
Figure 14: Power Supply

DOC-1017 Rev. A1 Page | 12
7. Flip the HDK power switch to the “ON” position.
Figure 15: Power Switch –ON
8. On the PC or laptop, open a serial terminal such as TeraTerm, select serial connection to the
enumerated COM port, and set the baud to 115200.
Note: The COM port will only enumerate while the HDK is powered. Once powered down, the serial
port will be disconnected.
