I confirmed this with ArmSoM. They purchased the original CoolPi 4B hardware design from CoolPi and confirmed that no hardware design modifications were made for the Sige7s. So the Sige7s uses the same hardware design as the CoolPi 4B, rather than being independently designed. Best regards, Jianfeng
