KEL-21L — 21.5" AI Panel PC for Vending Machines
The KEL-21L is a vending machine touch panel PC — an all-in-one PC, not a mini PC: the 21.5 inch Full HD touch screen, the computer and the serial, USB and LAN ports sit inside one fanless unit. As a 21.5 AI panel PC it adds a 6 TOPS NPU, so the machine recognises a QR code or a customer at the panel itself, with no server round trip. Designed and built in Thailand, so a port change or a repair goes to the engineers who drew the board.

KEL-21L or KEL-21 for a vending machine?
Take the KEL-21L when the machine has to recognise something at the panel — a customer, a QR code, an age check — because the 6 TOPS NPU does that on the device. If the panel only displays products and takes taps, the KEL-21 is the cheaper correct answer.
Which payment peripherals can it connect to?
It carries serial, USB and LAN, which is what card readers, bill acceptors and coin mechanisms connect over. Send the exact peripheral list with your quote request and we confirm the configuration before you order.
Is a fanless panel PC the right choice inside a vending machine?
Yes, and in a vending machine it matters more than anywhere else — a fan intake inside a sealed cabinet in Thai humidity is the part that fails first. The KEL-21L has no fan and no filter, and carries a 1-year warranty.
