Dicodes Flat Printed Circuit Board FL80_V2.1
(Preliminary, Subject to Change!)
The FL80 is an electronic circuit board for use in do it yourself electronic cigarettes, like box or tube
mods.
1. Size, Dimensions and Positions
The drawing below shows the overall size of dicodes FL80.
The board has several mounting options. When shipped, it has mounting strips on three sides,
each with several 2.1mm holes to mount it inside a housing using M2 screws or equivalent.
The mounting strips can be broken away individually. Without the strips the board has an
outline dimension of 17.2mm x 56.2mm (+-0.4mm due to break lines), or 17.2x63.7mm
respectively (with Micro-USB, see below).
There is also a separate metalized GND hole (battery minus), which gives the option to take
the GND connection from the housing if housing is connected to battery minus.
There are two USB connector option. One Mini-USB is on the bottom side of the board and
shows to the right, when you look at the board with the fire bottom in top position.
Note that the V2 boards default assembly is without the mini-USB plug populated (Beta
Version is always with mini-USB mounted).
The second option is to use the vertically mounted micro-USB plug on the extended part of the
PCB, which can be cut when not needed. The cut board has solder pads to reconnect it to the
main board with single wires. Such, the micro-USB board can be mounted elsewhere in the
housing.

- Page 2 On the FL80_V2 the Up-Button can have two different positions. One is the same as on the FL80_V1 (beta), option A, 3mm distance from the display frame. The second position is 2.5mm further away from the display frame, option B (total 5.5mm). This gives the option to use a rocker-button or larger up/down buttons.

- Page 4 2.2. The On-Board USB-Charger The On-Board charging circuit is an active switch mode battery charger in contrast to the often used linear charger on other circuits. The active charger has the main advantage that it is much more efficient. This enables the circuit to charge with much higher currents compared to a linear charger, and thus charging the battery faster.
- Page 5 Drawing 4 The Jumper pads are on the bottom side of the board as shown in the picture above. To connect an external USB plug or an external charger either use the 6-pin FPC connection (default: not populated) on the top side of the board or connect cables to the solder pads on the bottom.

Buttons There are three buttons on the board: One bigger fire button “right” to the display, and two up/down buttons “left” to it. The up-button has two possible assembly positions. The default position is next to the OLED display, and the center of the button has a distance of 3mm to the plastic frame of the display, which is the default position.
