UART COMMUNICATION BOX (JBD)

A compact USB-to-UART adapter (often called "UART box"), this module bridges your PC and JBD smart BMS—allowing you to monitor, configure, and update your battery management system directly via JBD’s software tools.

Physical Specs

Dimensions: Approx. 86 × 51 × 22 mm
Enclosure: Compact plastic case with simple labeling (“通讯盒”)
Cable: Includes around 1 m USB 2.0 cable for PC connectivity; front-end UART leads for BMS

Key Features

Standard USB 2.0 interface — Plug‑and‑play with Windows PCs
UART communication — Uses JBD’s protocol for reading cell voltages, currents, temperatures, SOC, alarms, etc.
BMS Parameter Configuration — Enables live monitoring and adjusting firmware settings (over/under-voltage thresholds, balancing parameters, sleep mode, etc.) via JBDTools
Firmware updates — Reflash BMS firmware directly from PC if new versions are available
