Here's how the Auvidea X241 and X242 carrier boards compare on those three dimensions:
| Spec | X241 | X242 |
|---|---|---|
| USB ports | 3 (2x USB 3.2 Type-A + micro USB OTG) | 5 (four USB-C + one USB-A) |
| M.2 slots | 1 (M-key 2280) | 2 (M-key 2280 + B-key) |
| Power input | 24–48 V | 24 V |
Key differences for a Thor build:
- USB: The X242 gives you two more ports and a different mix — four USB-C plus a single USB-A — versus the X241's two USB 3.2 Type-A ports and a micro USB OTG. auvidea.eu +1auvidea.eu ↗“2x USB 3.2 Type-A, micro USB OTG”auvidea.eu ↗“four USB-C and one USB-A port”
- M.2: The X242's second slot is a B-key in addition to the M-key 2280, so it can host more expansion than the X241's single NVMe (PCIe Gen5 x2) slot. auvidea.eu +1auvidea.eu ↗“one M.2 Key M 2280 NVMe”auvidea.eu ↗“M-key 2280, B-key”
- Power: The X241 accepts a wider 24–48 V operating range, while the X242 is listed with 24 V power input only. auvidea.eu +1auvidea.eu ↗“Operating voltage 24V - 48V”auvidea.eu ↗“24V power input”
Both are Auvidea Jetson Thor carrier boards with the same 104.6 × 125 mm dimensions, dual 10GbE, HDMI, and 2 CAN ports. auvidea.eu +3auvidea.eu ↗“dual 10GbE (RJ45), HDMI”auvidea.eu ↗“125”auvidea.eu ↗“dual 10GbE, HDMI”auvidea.eu ↗“125”
One compatibility note: the X241 is described as a carrier for the Jetson AGX Thor module, while the X242 is tied to the Jetson T5000 (Thor) module — specifically the Jetson T5000 128GB — so your module choice may decide between them as much as the I/O does. auvidea.eu +1auvidea.eu ↗“carrier board for the NVIDIA Jetson AGX Thor module”auvidea.eu ↗“Jetson T5000 128GB”
