All instructions must be read and followed in detail for safe use of the equipment. Use of this equipment in any other way can result in electrical fire and shock hazards or explosion hazards from battery overcharging. The Hologram Dash is intended for integration into electronic systems only by experienced professionals and individuals trained in electronic design principles or electrical engineering. Users are required to have a basic understanding of electronic safety precautions and understand that although normal operation does not present hazardous voltages or currents, that improper handling of the devices can result in hazardous currents. The Hologram Dash is not designed to be used for life-support systems or real-time systems that could induce physical harm or property damage if the hardware or network connections fail. The end user assumes all liability for systems implemented with the Hologram Dash.
Hazards include but are not limited to:
- Connecting the on-board jumpers incorrectly.
- Shorting the user pins (for example, placing the board on a conductive surface, such as a metal table).
- Shorting the leads of components on the board.
- Connecting the device to external devices that supply or consume hazardous voltages / currents.
- Connecting the battery, USB inputs, or any other user-pin to a conductive surface that can be touched by the operator.
- Using a battery that is not LiIon or LiPoly.
- This equipment has not been assessed for compliance with safety requirements related to use with batteries. If batteries are intended to be matched to this unit by the end user further assessment of the combination of this equipment with any battery is required and includes the need to use only EN/IEC 62133 certified batteries and to confirm battery mfr specified charge voltages and charge current rates are not exceed by the charging circuit provided from this equipment. testing for compliance with 4.3.8 of En 60950-1 would be required. Confer with Hologram technical support services to obtain battery charging circuit specifications provided by this equipment - after suitable batteries are matched an explosion hazard exists if batteries are replaced with an incorrect type of battery. Dispose of all batteries per the manufacturers instructions.
- Using an expired battery, a battery that isn’t charging correctly, or a battery that is bulging.
- Using the device in a hazardous environment.
- All connections to the unit, including power supply, must be from secondary circuits separated from mains by double or reinforced insulation, or by a ground shield.
- Warning – fire hazard - the unit is not to be powered simultaneously from GND and USB_5V (See Pinouts Left Connector Pin 1 and 2) and through a power supply connected to the micro-USB connector. Use only one of these connections to source power to the unit.
- Improper Configuration of the on-board jumpers can result in a fire, electrical hazard, and exploding batteries (See Jumper Settings).
- When supplying the unit through pins GND and USB_5V (See Pinouts Left Connector Pin 1 and 2) for purposes of powering the equipment, a user provided 3A max fuse must be provided in the power supply circuit feeding the unit.
The Hologram Dash as a bare PCBA is designed for indoor use between 0-55 degrees Celsius. The devices are not designed to withstand material contact with moisture or any other conductors, aside from intended use of the user pins, Micro-USB, or battery terminal. The Hologram Dash may be installed into appropriate enclosures that can protect the device from heat, cold, moisture, and humidity for Industrial use.
Absolute Maximum Ratings
Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating section may cause permanent damage. These are stress ratings only. Operating the device at these or at any conditions other than those specified in the Operating Conditions should be avoided. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

Flash and RAM Specifications
User: 1024KB Flash, 32KB RAM System: 256KB Flash, 24KB RAM Note: 32KB of Flash is unusable due to the bootloader
Improper Configuration of the on-board jumpers can result in a fire, electrical hazard, and exploding batteries. The configurations must either be placed in DC 5V Mode or Battery Mode.
Buttons / LEDS
The only LEDs that are active on the Dash are the System and User IC LEDs. The rest have had their current limiting resistor removed to conserve energy. The Dash has three buttons:
- Program: Pressing this will enter the Dash into USB program mode
- User IC reset: This will cause a hard reset on the user IC.
- System IC Reset: This will cause a hard reset on the system IC.
For specific values, see Operating Conditions. The connector Pinouts are referred to the “Left” and “Right” side, when looking at the side with the modem, with the antenna facing upwards to the literal clouds, referencing the literal cloud. Hologram Pinout Legend
