+The two screw terminal blocks are mounted on each side of the carrier and provides easy connections that can be fastened with a simple flathead screwdriver.

+There is also two extra GND connectors for your convenience.

+
+The prototyping area is **9x8**, with a pitch of **2.54 mm**. While not huge, it is perfect for mounting smaller circuits ICs, sensors or other components.
+
+An example on how much you can fit on the area is:
+- A ULN2803A motor driver for stepper/DC motors.
+- A connector row.
+- A square RGB LED.

 ## Considerations
 
 As the pinout slightly differs from one Nano board to another, there are some important considerations to take into account. This sections lists out all considerations to take into account when using this product.
 
 ### RST Pin
 
-![RST pin on the carrier.](assets/nst-terminals-1.png)
+![RST pin on the carrier.](assets/nst-rst-pin.png)
 
 The pin marked **"RST"** on the board stands for **"reset"**. On the Nano Screw Terminal, it is disconnected by default. The reason behind this is that the function of this pin varies from board to board. 
 
-An example of this is the [Nano RP2040 Connect](https://store.arduino.cc/nano-rp2040-connect), where this pin is named **"REC"** as in **"recovery"**. If this pin had been connected, it would have constantly resetted the board.
