200 Watt Variable Power Module with Temperature Protection and USB
The DNA 200 is a power regulated digital switch-mode DC-DC converter for personal vaporizers.
It features Evolv's patented Wattage Control, Temperature Protection, Preheat, Digital User Controls,
OLED Screen, Onboard Buttons and Synchronous Rectification for maximum battery life and minimal
heat generation. The DNA 200 runs from a 3 cell lithium polymer battery, and features cell-by-cell
battery monitoring and integrated balance charger. The USB port and Evolv's EScribe software can be
used to customize or monitor the user experience. It is the most advanced personal vaporizer controller
ever made.

Page 3: Temperature Protection
Temperature Protection The DNA 200 directly measures and limits the temperature of the heating coil during operation. By preventing the coil from becoming too hot regardless of fluid, wicking or airflow, a variety of undesirable situations can be prevented. For example, appropriate temperature settings will prevent the wicking material from charring, which compromises taste and introduces unintended chemicals into the vapor. -
Page 4: Attaching A New Atomizer
If a new atomizer is attached to the DNA 200 before it has cooled down, the temperature may read and protect incorrectly until the new atomizer cools. -
Page 5: Operation
Operation Basic operation of the DNA 200 is as follows. To wake the device from power off state, tap the Fire button. To generate vapor, press the Fire button. To change the wattage setting for more or less vapor, click or hold the Up and Down buttons. -
Page 6: Modes
To do so, while locked hold both the Fire and Up buttons for two seconds to enter Resistance Lock mode. In this mode, the DNA 200 will use the present atomizer cold resistance without refinement until the atomizer is disconnected or the resistance lock is disabled. -
Page 7: Error Messages
Weak Battery: The battery needs to be charged, or a higher rate battery needs to be used. If this happens, the DNA 200 will continue to fire the atomizer, but will not be able to provide the desired wattage. The Weak Battery message will continue to flash for a few seconds after the end of puff. - Page 8 Charger The DNA 200 has a built in 1A USB charger. It automatically detects the type of USB power supply it is connected to, so it can be plugged into standard PC USB ports or higher power chargers. The max charge current is based on the cell capacity as programmed in EScibe.
- Page 9 Escribe Escribe is a software package used to configure and modify the operation of your DNA 200. It installs on a Windows PC and connects to your DNA 200 using the USB port. When you connect your DNA 200 to the PC, press the “Connect and Download Settings” button to download the settings presently on your device to Escribe.
- Page 10 Screen Tab The Screen tab allows you to change the characteristics of the screen, and also to change or replace any of the status and error messages with inages. Images must be 128 x 32 pixel monochrome bitmaps. Research Tab The Research tab is primarily for data logging or restricting the device for use in research.

Page 13: Wiring
Wiring The atomizer is connected to the OUT pad. If the DNA 200 is not being grounded through the mounting screws, the GND pad should connect to the negative side of the connector. The battery is connected to the B+ and B- terminals. It is important to use appropriately sized wire when using the DNA. -
Page 14: Mounting
With careful design, the mounting pads can be used to ground the chassis to the DNA 200, and pass the output current through chassis to the connector. However, if using this method, ensure that the PCB remains in good contact with the board at all times. Split lock... -
