+* [[Rock3/CM3/raspcm4io/getting_started | Getting started with Radxa CM3 + Raspberry Pi Compute Module 4 IO Board ]]
-** CM4 IO  is equipped with a full sized HDMI connector. HDMI capable monitor is recommended.
-** HDMI EDID display data is used to determine the best display resolution. On monitors and TVs that support 1080p (or 4K) this resolution will be selected. If 1080p is not supported the next available resolution reported by EDID will be used. This selected mode will work with MOST but not all monitors/TVs.
-*Micro USB
-**If you want write image on CM4 IO  from USB port , commands you need an USB Male A to Micro USB cable to connect CM4 IO  and PC.
-=== Optional ===
-* microSD Card Reader
-** For flashing the image into microSD Card
-* USB type A to type Micro USB
-** Write image on CM4 IO  from USB port
-*  USB to TTL serial cable
-** This is needed for serial console.
-*  Ethernet cable
-** CM4 IO  supports Internet access via WIFI or Ethernet.
-** An Ethernet cable is used to connect your CM4 IO  to a local network and  the Interne
-* Audio cable
-** Audio can be played through speaker or headphones using a standard 3.5mm jack.

-==== More details about 40-pin Header ====
-* Pins marked with color orange are designed for debug console.
-* PWM:x7,PWM0/PWM1/PWM2/PWM3/PWM6/PWM7/PWM11
-* SPI:X2,SPI0/SPI3
-* I2C:X2,I2C2/I2C4
-* UART:X2,UART0/UART2
-* ADC:X1, SARADC_IN3
-* I2S:X2, I2S1/I2S2
-=== IO Voltage ===
-RK3566 have three IO voltages, 1.8V/3.3V. For CM4 IO, the high level voltage of GPIO pin on 40-PIN HEADER is 3.3V.
-<pre>
-| GPIO       | Voltage Level | Tolerance |
-| ---------- | ------------- | --------- |
-| SARADC_IN3    | 1.8V          | 1.98V     |
-</pre>
-=== GPIO number ===
-Rockchip RK3566 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:
- GPIO0_A0 ~ A7
- GPIO0_B0 ~ B7
- GPIO0_C0 ~ C7
- GPIO0_D0 ~ D7
- GPIO1_A0 ~ A7
- ....
- GPIO1_D0 ~ D7
-The GPIO number can be calculated as below, take GPIO4_D1 (PIN26 on 4-0PIN HEADER) as an example:
- GPIO4_D1 = 4*32 + 3*8 + 1 = 153
- (A=0, B=1, C=2, D=3)
-To set GPIO4_D1 output
- cd /sys/class/gpio
- echo 153 > export
- cd gpio153
- echo out > direction
- echo 1 > value     # output high
- echo 0 > value     # output low
