CB Series Datasheet

Description
CB series platform is constructed by a 32 bit RISC core, a 16 bit ADC, and lowpower circuits. In the normal operation, the SpectraSmart software can communicate
with CB series through a high speed USB2.0 port on PC. The programmable CCD &ADC timing generator inside CB series can control the different CCD types and read theADC data back in high data rate. CB series also provides several interfaces tocommunicate with external devices, like UART.

The user can buy the corresponding cable to connect to CB Series UART port. The above
picture is an example to use the cable with 1.0 mm pitch header to 2.0 mm pitch header.
(like JST PH connector) If the USB port and UART port are used at the same time, theUART +5V connection needs to consider the connection or disconnection.
