There are three models of ROCK 3, model A and model B. Model A is a stripped down version of model B in smaller size and less features. The differences are:

Model A vs. Model B

Model	RAM	Ethernet	WiFi/BT	eDP	LVDS	Cellular 4G/5G	Heatsink	Size
ROCK 3 Model A	2GB, 4GB or 8GB	1x GbE	N/A, via M.2	N/A	N/A	N/A	Small attach to CPU, with fan	85 * 56 mm
ROCK 3 Model B	4GB or 8GB	2x GbE	WiFi 6/BT 5	Support	Support	Support	Big with mount, with fan	100 * 75 mm

Change lists

Model A

v1.1

- First public version, only few are made, some early developers receive samples

v1.2

Changes based on v1.1 with community suggestions:

Add a USB hub for M.2 E Key USB for BT
Add a PWM fan connector
Add silkscreen for eMMC module
Change M.2 E key mounting to standard M.2 screw
Rotate the logo to align with the CPU silkscreen and WiFi cards

v1.3

Changes based on v1.2 with manufacturing improvement:

change resistor 240R footprint from 0402 to 0201
change capacitor 2.2uF, 22uF footprint from 0805 to 0603
headphone jack footprint improvement
Q3 MOS WNM2021-3/TR SOT-323 change to triode 3904 SOT23-3
