+
+Overview
+********
+
+The KB1062_EVB kit is a development platform to evaluate the
+ENE KB106X series microcontrollers. This board needs to be mated with
+part number KB1062.
+
+Hardware
+********
+
+- ARM Cortex-M3 Processor
+- 256KB Flash and 64KB RAM
+- ADC & GPIO headers
+- SER serial port
+- FAN PWM interface
+- ENE Debug interface
+
+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+System Clock
+============
+
+The KB106x MCU is configured to use the 48Mhz internal oscillator with the
+on-chip DPLL to generate a resulting EC clock rate of 48MHz/24MHz
+See Processor clock control register (refer 5.1 General Configuration)
+
+Programming and Debugging
+*************************
+
+.. zephyr:board-supported-runners::
+
+Flashing
+========
+
+If the correct headers are installed, this board supports SWD Debug Interface.
+
+To flash with SWD, install the drivers for your programmer, for example:
+SEGGER J-link's drivers are at https://www.segger.com/downloads/jlink/
+
+Debugging
+=========
+
+Use SWD with a J-Link
