 **Note on Programmers and USB/Serial Bridges for ESP32-CAM**
 
-The ESP32-Cam doesn't have an onboard USB/Serial converter, but is commonly shipped with an ESP32-CAM-MB interface that can simplify programming. Unfortunatly the ESP32-CAM-MB also makes it very difficult to access IO pins, so it's possible to us a different USB/Serial interface. (A CP2104 is a good option as it's low cost, provides both 5v and 3.3v and also allows gives the best compatibility with wallet software)

 Once you have flashed the firmware, it's also possible to run the device without any USB/Serial bridge and supplying 5v directly to the ESP32-Cam. (This obviously prevents it being used via USB)

 In addition to the 'official' ESP32-WROVER-CAM boards from Freenove, there are also a number of readily available, low cost 'clones'.
 
-Some of these clones have will have different ports (Freenove with USB-C and cloes with MicroUSB), the camera position is slightly different (Hence why the example 3d printed cases have a rather large camera hole) and they also sometimes have slightly different startup behavior.
+Some of these clones have will have different ports (Freenove with USB-C and close with MicroUSB), the camera position is slightly different (Hence why the example 3d printed cases have a rather large camera hole) and they also sometimes have slightly different startup behavior.
 
 Some clone boards won't boot properly until you press the EN/RST pin after powering up the device. If your board behaves in this way, the simplest solution is to connect the EN/RST pin on your ESP32-WROVER-CAM board to a spare button on your LCD hat. (Pressing this button will then allow you to boot/reset the device at any time)
