No, the Nextorage NX-A2PRO 160GB CFexpress Type A is not compatible with the Panasonic LUMIX GH7.
Panasonic LUMIX GH7's Slot 1 is CFexpress Type B only. Panasonic's own spec sheet states 'Card slot 1: CFexpress Type B card' -- CFexpress Type A uses a physically different, smaller connector and cannot be inserted into this slot.
