Which processor and memory configuration should be ordered for K20A?
The standard K20A uses Core i5-1235U, 8GB RAM, a 128GB SSD and Windows 11 Pro 64-bit. Core i7-1255U, 16GB RAM and Windows 10 Pro 64-bit are documented options.
Why choose the 12.2-inch K20A instead of a smaller Windows tablet?
The 12.2-inch 1200 × 1920 screen gives engineering drawings, diagnostics and detailed forms more working area. The trade-off is a larger 339.3 × 230.3mm enclosure and 1,500g weight, so handling and mounting should be planned accordingly.
Does K20A support hot-swapping the 6,300mAh main battery?
K20A has a built-in 700mAh battery and a removable 6,300mAh main pack, but uninterrupted operation during replacement is not stated. The product should therefore be described as dual-battery with a removable main pack, not hot-swappable.
Which industrial expansion board can K20A use?
One board is selected from Gigabit RJ45, DB9 RS232, additional USB 2.0 or Honeywell N3680 QR/2D scanning. The order should identify one required function and the related driver/cable package.
Which GNSS and identity options are available?
Fingerprint is built in. u-blox M7N is standard for GPS/GLONASS, M8Q is optional for GPS/BeiDou/GLONASS, and NXP300 NFC is an optional contactless-input module.
Which K20A accessories should be specified for deployment?
The 65W adapter is standard. Pogo dock, stylus, spare main battery, vehicle mount and car charger are project options and should be listed by exact item and quantity in the quotation.
