 ===== Connections =====
   * **USB:** 3 × USB-A 2.0, 1 × USB-C
+      * **The USB ports can reach up to about 10 MB/s.**
     * One of the USB-A ports is internal. Only the top internal one works
     * The internal USB-C port is used for the keyboard
     * Note: these ports are intended for use with mass storage devices only. It has been reported that USB keyboards do work. Other devices **do not** work with USB (like mouse, gamepad, joystick)
   * **MicroSD:**
     * Internal slot (card sold separately)
+      * **The SD card is working in 1-bit SPI mode at 25 Mbps (3.125 MB/s), thus this is more then 3x slower than USB.**
   * **Display Output:**

-Despite being labeled officially as **'a headphone jack'** there are strong indications that it is not a good idea to use it as an headphone jack. __It is presumed to damage the device__. - Advised is to use it as an 'line out' instead. And to use an amplifier for headphones between it.
+Although a stereo audio jack may physically accept a 3.5 mm headphone plug, using it this way is not recommended and **may potentially damage the device**.
+It is advised to treat this connector strictly as a **line‑out** and use a headphone amplifier between the device and your headphones.
