- On board Real time clock (RTC) keeps the time going even when the Arduino is unplugged. Note: The RTC requires a small coin cell battery (not included). The board will still operate without the coin cell battery. Once installed the RTC battery will last for years.
- Adafruit libraries and example code for both SD and RTC mean you can get going quickly
- Prototyping area for soldering connectors, circuitry or sensors
- Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported.
- Requires soldering of header pins

This data logging shield is designed for the Arduino platform and is utilized on our main OLHZN flight computers to save sensor and other telemetry data in 1 second increments to an on-board SD card. -
Our main flight computer is based around the Arduino Mega platform. It is a very reliable platform and works well for logging telemetry and broadcasting positioning reports via APRS over amateur radio frequencies. When purchasing any Arduino product, be sure the Arduino is genuine and not a fake, replica or counterfeit device. Fake and replica Arduinos are generally not as reliable as they use cheaper parts, particularly when it comes to power regulation. For details on how to check if your Arduino is genuine see this Arduino page. -
Experimental. These circuit boards are used by the OLHZN High Altitude Balloon team for high altitude weather balloon tracking. However, the circuit boards are considered experimental and may suffer from unforeseen errors or undiscovered technical deficiencies. An amateur radio license from the FCC is required to operate these in the United States and many other countries worldwide. Check your local governing body for details. Due to the experimental nature of these circuit boards, returns are not accepted on this product. The bare circuit board is the least expensive option, but you would need to purchase the assembly parts yourself. The source code, parts list and assembly instructions can be found at https://github.com/OverlookHorizon/OLHZN_Track If you want to have all the parts included or have the board pre-assembled for you, you may select those options too, if desired. They are not required, though. You can source the parts and build the entire board yourself for the lowest cost. -
This GPS breakout board module is utilized on all the OLHZN high altitude weather balloon flights. It will register altitude and positioning reports up to 160,000 FT (48,768 m), but you must be sure to enable "Flight Mode" (Mode 7) via software on startup. The active antenna is a must have if you're utilizing an on-board action camera. The active antenna will ensure that electromagnetic interference from the action camera(s) will not disrupt the GPS signal reception.- Micro USB port allows you to connect the GPS module to your computer without USB-TTL cables.
- The GPS module also has a ceramic passive antenna so you can utilize the module without the external antenna, if desired.
- The SMA port allows you to conveniently connect the 3m Active Antenna for a much stronger satellite connection.
- The TTL port (header pins) allow you to conveniently connect this module to an external single chip microcomputer.
