What do the kits include?
• the full kits ("kit with plastic housing" in the dropdown list) include everything that the assembled models have (the engraved plastic housing as well) but the buyer needs to assemble the timer, which may require some soldering
• the kits without housing ("kit without plastic housing" in the dropdown list) include everything that the assembled models have except for the plastic housing (ready-made PCB with display, wires, buttons and, for models AST-311 and AST-321, the key switch); and assembly may require some soldering
• the "AST-3XX PCB (mainboard)" only includes the ready-made (soldered) PCB with the display but no buttons, wires or whatsoever; assembly of an airsoft timer using this PCB may require some soldering as well
• all kit models include a printed assembly guide in English
