25 | 0,4x0,4; Staerke: 0,05 (CAN/IO) |
||
26 | |||
27 | 14 | Maximilian Seesslen | Geht noch, nicht kleiner: |
28 | 15 | Maximilian Seesslen | *0,6x0,6; Staerke: 0,05* (CANDisplay::Eval; Miniminutnik) |
29 | 2 | Maximilian Seesslen | |
30 | 17 | Maximilian Seesslen | Geht noch, eher nicht kleiner, manche Labels nicht mehr eindeutig: |

52 | h2. Standard LEDs; 2V @ 3V |
||
53 | |||
54 | 120 Ohm: very bright |
||
55 | 240: bright, ok for blinking, still to bright for permanent on |
||
56 | 480: should be the usual case |
||
57 | 1k Ohm: very dark. eg. ok for power LED |
