For sighting, a cheap 4.3-inch FPV monitor with a resolution of 480x272 is used, by attaching a camera with a viewing angle of 110 degrees of the PAL or NTSC system to it

Yes, the exposure meter and rangefinder are based on arduino pro mini, link to arduino software https://drive.google.com/drive/folders/1z0SUZkfYGmW-IWVCd1P3fhdQxiY3AcFP?usp=drive_link

Exposure limits EV0 - EV14.5 Distance measurement 0 - 12 m. Any lens from a Mamiya press camera

My camera is 6x12
