The MAX6960 EV system is a PC-controlled LED dis-
play system consisting of a MAX6960 EV kit and the
Maxim CMODUSB serial interface board.
The CMODUSB serial interface board uses a propri-
etary design to provide SPI™- and I
interfaces to demonstrate various Maxim devices.
Maxim reserves the right to change the implementation
of this module at any time with no advance notice.
The CMODUSB board uses a MAX1658 linear regulator.
Jumper J1 selects between a 5V or 3.3V system supply
voltage. Do not plug a wall cube into the P1 power jack
because power is provided from the USB port.
Table 2. CMODUSB Jumper J1 (System
Supply Voltage)
The MAX6960 EV kit contains four MAX6960 devices
(U1–U4), a 16 x 16 dot-matrix display (D1–D4), a step-
down voltage regulator (U12), a 4MHz oscillator (U10),
and logic buffers (U5–U9, U13). The MAX6960 EV kit
requires a +5V supply (rated for 2.5A per EV kit) and up
to five MAX6960 EV kits can be cascaded allowing the
user to evaluate up to 20 MAX6960 devices.
Tables 3 through 19 explain the functionality of each
jumper when using only one MAX6960 EV kit.

*Make sure the J1 jumper on the CMODUSB board is in the 2-3
position when using the MAX6960 EV kit.
*Default configuration.
