ZICM2410-EVB3 Hardware Reference Guide
Microphone input and Headphone output for connection when using the evaluation
board's voice / audio features.
ZICM2410 module. The DUT of the evaluation board
3 ea 10-pin DIP Switches used for disconnecting the evaluation boards connections
to the various on board features (i.e. LEDs, switches, etc.).
ISP Mode Switch: 2-position slide switch to control ISP mode
'ISP' position is used for downloading application firmware to the ZICM2410.
For normal operation, the switch should be set to the 'NORMAL' position.
Button switch to reset the device MPU (Active Low)
Four indicator LEDs for GPIO output tests
Push Button Switches connected to General Purpose I/O (GPIO) Ports:
When a button is pressed, the signal '0' is applied to the corresponding port pin;
otherwise, a value of '1' is applied. Switches #3 and #4 can be configured as
external interrupts to the 8051 microcontroller.
Holder for 2 ea. 1.5 Volt Type AA Batteries
Input for a 5.0 – 9.0 Volt DC Power Supply
This three position slide switch is used to select the power source for the evaluation
board. In the position 'VREG', power is supplied either through the USB port or from
a power supply inserted in the DC Jack. In the 'VBAT' position, batteries provide the
power.
LED indicates when DC power is turned on.
Port to connect the evaluation board through a USB cable to a PC.
Variable Resistors for testing ADC functions in the ZICM2410 module
For measuring operating current of the module under various conditions
Silicon Labs CP2102 USB to UART Bridge IC: Converts I/O from USB to UART.
1 ea. 4-pin header to provide a convenient method to monitor or connect to an
Analog input.
3 ea. 8-pin header to provide a convenient method for to monitor or connect to a
selected Digital GPIO port.
Onboard ROM for storing additional information.
Onboard Voice CODEC used for A/D and D/A conversions of Voice / Audio.
4-pin header for direct powering of the EVB, bypassing the internal regulator
