JKBMS JIKONG Display Guide: B/BD vs. PB Compatibility
Share
Quick answer: B/BD boards use a B/BD-compatible 4.3-inch, 3.2-inch, or 2.0 display. PB boards use a 4.3-TTL or 7.0-TTL display. The B/BD 4.3-inch display and PB 4.3-TTL display are different and cannot be interchanged.
This JKBMS JIKONG guide helps you identify your protection-board series and choose the matching display before ordering.
Identify your protection-board series
Check the product name, label, or order details to confirm whether your board is B/BD or PB. Then select a display listed for that series.
