2 min read · English documentationWhen the onboard computer must be mounted securely, observe the following important precautions.
-
Four (4) bolt mounting holes are provided on the bottom of the device for secure installation.
-
After installation, make sure that the air inlet on the top and the air outlet on the side are not obstructed. Poor heat dissipation will reduce device performance.
-
Use only the supplied M2.5 × 3 mm mounting bolts. Bolts that are too long may damage components inside the enclosure.

Hardware Interface Description
Important precautions:
$\color{#FF0000}{1. Except for the Ethernet port, all device interfaces can supply power externally. The UART0 external output is 5V0.}$
$\color{#FF0000}{The other interfaces provide a 3V3 external output. Refer to the corresponding interface section for output current ratings.}$
$\color{#FF0000}{2. Confirm all of the following before connecting a peripheral to any interface:}$
$\color{#FF0000}{a. The peripheral's voltage pin must be an input. Do not connect the peripheral to Allspark if its voltage pin is an output.}$
$\color{#FF0000}{b. Double-check that the peripheral's voltage pin and GND pin are connected correctly before powering on the device.}$
$\color{#FF0000}{c. The rated external output power of 3V3 is 9.9 W. The combined output current of all interfaces providing 3V3 must not exceed 3 A.}$
$\color{#FF0000}{d. The rated external output power of 5V0 is 25 W. The combined output current of all interfaces providing 5V0, including the USB ports, must not exceed 5 A.}$
