==FAQ==
Q1:Which GPIO can be used after use the CM4 to CM3 Adapter?
 
A: CM3 has 46 GPIOs, ranging from GPIO0~GPIO45; while CM4 has only 28 GPIOs, ranging from GPIO0~GPIO27; so if you want to use CM4 to replace CM3, GPIO can only use GPIO0~GPIO27, because CM4 has only 28 GPIO, please refer to the datasheet of CM4 and CM3, thanks!
 
Q2: Does the CM4 to CM3 Adapter support CM4 Lite?
 
A: Yes, you can use the CM4 to CM3 Adapter covert CM4 Lite to CM3 Lite. But please make sure your CM3 IO board is support the CM3 Lite, then you can use it.
