3 Pinout and Remapping

Pinout and Remapping Area, Different Types of Remapping.

Tip: The mapping between Explorer and any Curiosity Nano development board can be found in the Curiosity Nano Explorer Pinouts document.
Figure 3-1. Pinout, Remapping Area and CNANO Socket
Board Overview
Connections to the CNANO socket are divided into five sections - COM, analog, IO1, IO2 and IO3. Standard functionality is assigned to each pin in the COM and analog section Curiosity Nano development boards. Pins in the I/O sections are numbered with a <section><pin-number> format, ex: “IO 26” indicates section 2 pin 6.
Info: Curiosity Nano development boards with low pin count microcontrollers may not implement the standard functionality in the COM and analog sections.

Tip: Connect your measuring tool to the innermost pin header for easy access to any signal on the Explorer. Use the custom test points for access with longer measurement probes.

3.1 CNANO Socket Remapping

The Explorer’s connections to the CNANO socket are fully remappable. Any peripheral can be connected to any pin on the socket.

Tip: Peripheral connections are labeled on the silkscreen.

3.2 Direct Remapping

Many peripherals on the Explorer can be remapped by connecting a pin directly to the CNANO socket using a jumper wire. For example, if your CNANO's microcontroller has a DAC (Digital-to-Analog Converter) output, you can directly connect it to the speaker amplifier.

3.3 Custom Test Points

The Explorer features four customizable test points available on the board edge. The test points are labeled TP1, TP2, TP3 and TP4 on the silkscreen.

Easily measure any signal by connecting a jumper wire between the innermost pin header in the remapping area and a test point.

Tip: A pin header with ground connections is available next to the test points.
