MCU = ?????????????????? Connector recommendations The IDC connector supplied with the GEMINI-1 programmer is ‘bump’ polarised so that it can not be inserted the wrong way around in a polarised socket. If the connector used on the target system is not polarised, it is advised that measures are taken to prevent the connector being plugged in the wrong way around. -
Page 27: Target System Requirements
These can be found in the relevant microcontroller data sheets. • Power The GEMINI-1 requires a regulated DC supply to operate. This supply can be taken either from the user target system or an external power supply unit (PSU). The programmer should operate correctly between the specified operating voltage limits (see hardware specifications). -
