 Gateworks has very sturdy and robust power supplies that typically use a wide voltage DC input (8-60VDC for most boards). Gateworks will typically put a series diode for reverse polarity protection and a TVS for overvoltage transient protection.
 
-For example, here is more specifications on a Ventana GW5220:
- * Gateworks has power conditioning circuitry on the VIN input which consists of a reverse polarity protection diode, a couple of X2Y EMI supression caps and a transient voltage protection diode which kicks in at 60V. Gateworks has had many customers use our boards for in vehicle applications with good results. The TVS device is the SMAJ58A. It provides IEC61000-4-2 ESD, IEC61000-4-4 EFT and  IEC61000-4-5 surge protection.
+For example, here is more specifications on a sample set of SBCs:
+ * Venice GW7100: This uses a Vishay SiC467ED-T1-GE3 supply up to 6A at 98% efficiency with over current protection (OCP), output overvoltage protection (OVP), short circuit protection (SCP), output undervoltage protection (UVP) and thermal shutdown (OTP). A TVS diode is used to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events( D15). This is a Littelfuse SMAJ58CA TVS Diode designed specifically to  It supports IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact). ESD protection IEC 61000-4-2. EFT protection IEC 61000-4-4. A Schottky Rectifier diode is also used to provide reverse polarity protection (D38). Several ceramic capacitors are also used as bulk decoupling to stabilize the input voltage for the switching regulator, these capacitors also act as a low-pass filter.
+ * Venice GW7200: Very similar to the above GW7100, except two SiC467 supplies are used (one for 5V and one for 3.3V). The same SMAJ58CA TVS Diode is used (D31). 
+ * Ventana GW5220: Gateworks has power conditioning circuitry on the VIN input which consists of a reverse polarity protection diode, a couple of X2Y EMI supression caps and a transient voltage protection diode which kicks in at 60V.
