1. Features
• USB interface
• Full USB V1.1/2.0 compliance
• Full USB HID 1.1 compliance
• Three analog potentiometer axes with 8 bit
resolution each (100k pots required)
• Available with support for either up to 8 buttons
or up to 16 buttons
• Autocalibration and autocentering
• Single +5V power supply
1.1 Variants
JW24MOD-A8-8 supports up to eight buttons
which close to Ground.
JW24MOD-A8-16 supports up to 16 buttons
arranged in a matrix of 4x4. Diodes are required
for proper operation of the matrix.
1.2 Custom variants
Custom adaptions are available on request.
2. Functional overview
The JW24MOD-A8-x comes equipped with
JoyWarrior24 A8-x chips. It allows direct
connection of up to three 100k potentiometers and
either up to 8 or up to 16 buttons depending on the
JoyWarrior variant used.
The JW24MOD-A8-x has been optimized for the
use with 100k pots, any significant deviation (>±
20%) from this value results in reduced resolution
of the joystick movement.
3. Connecting the electromechanics
The module has the signal names printed next to
the solder pads.
K1 is for the connection of the USB cable.
K2 is the group of signals to connect the pots. AZ,
AY, AX are the respective center taps for the three
pots. All three taps of the pots need to be
connected.
K3 and K4 are for the connection of the buttons. In
case of a JW24MOD-A8-8 the buttons have to
close to GND. For the JW24MOD-A8-16 the
buttons are arranged in a 4x4 matrix. To ensure all
buttons can be pressed in any combination it is
necessary to insert diodes in series with every
button. The kathodes of these diodes have to
connect to the Y lines.
JP1 is an optional jumper to enable the Raw mode
of the JoyWarrior for testing purposes.
For further details please refer to the JoyWarrior
datasheet.
Soldering wires to the module should be done
carefully to avoid separating the pads from the
PCB due to overheating or mechanical stress.
4. Mechanical dimensions
The mounting holes are 2.5mm in diameter.
The solder pad holes are 0.9mm in diameter.
Tolerances:
Hole diameters: -0.05 +0.1mm
Hole positions: ±0.05mm
Outer contour: ±0.2mm
5. FCC / CE
The JW24MOD-A8-x is sold as a module to be
integrated into a device. As such it can not be FCC
or CE approved.
Code Mercenaries has excerted greatest care in
designing this module to minimize RF emission
and assure stable operation. Though the use of
proper cable materials and correct integration into
a device is crucial to assure product safety and
interference free operation.
The integrator who assembles the module into a
device has to take care for appropriate testing and
safety measures.

6. Ordering information
The modules listed here are standard products.
Customized modules are available on request.
6.1 Packaging info
The modules are produced in larger boards
consisting of 56 modules each. For custom
versions it is only possible to produce in multiples
of 56, though the actual shipping quantity may
vary from this as faulty modules may be rejected in
production testing.
6.2 USB VendorID and ProductID
By default all JoyWarrior modules are shipped
with the USB VendorID of Code Mercenaries
($7C0 or decimal 1984) and a fixed ProductID.
On request modules can be equipped with the
customers VendorID and ProductID. VendorIDs
can be obtained from the USB Implementers
Forum <www.usb.org>
Customized modules are subject to minimum order
quantities, contact <sales@codemercs.com> for
details.
Following are the ProductIDs:
JW24MOD-A8-8 $1104
