==FAQ==
1. Why when multiple X835 boards are stacked together, except for the first X835 at the top, all other X835s are not powered on? Answer: <span style="color:red;font-weight:bold">When multiple X835 boards are stacked, except for the first X835 board on the top, the two jumpers of the other X835 boards need to be plugged in</span>, otherwise they will not be powered on. 2. How to use external power switch for X835 board?
Answer: 1. Please use latching switch only and not use momentary switch; The jumper socket fitted for "PWR ON" must be removed when using an external latching power switch. 2.All the board, cable, jumper connections must be under power-off station.
Answer: The X835 reuqires 12Vdc +/-5% , ≥3A power supply with DC jack - 5.5x2.5mm.
Answer: Whatever to use with X735 or not, the PSU must be connected to X835 DC 12V IN port, not X735 or Raspberry Pi.
Answer:
Answer: The "L-SW" pin must be shorted when use X735 latching switch port to connect an external latching switch.
Answer: Connect the power switch to X735 "Latching Switch" port when use with X735.
8. How many X835 borads can I stack?
In theory, it can stack as many X835 as possible, but considering the speed of USB3 and power supply issues, it recommend that just stack about 3-5pcs X835.
