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
