ESP32-S3 GPIO expansion board for multiple pin spacings

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The ESP32-S3 GPIO Expansion Board is an expansion board for ESP32-S3 development boards that provides easy access to GPIO connections, power supply and ground. The board is designed for prototypes, experiments and projects where multiple external components need to be connected to an ESP32-S3 board.

The expansion board has multiple pin positions, allowing it to be used with ESP32 development boards having different spacing between the pin rows. The board has pin spacing of 25.4 mm and 33.02 mm and is designed for flexible connection of compatible development boards. Development boards with other pin spacing, such as 30.48 mm, require corresponding hole positions to be available on the expansion board.

The board has a 2.1 x 5.5 mm DC connector and is designed for an input voltage of 6.5 to 9 V DC. The input voltage is first regulated to 5 V by a 78M05 regulator. This 5 V supply is also used to power the switching TLV62569 regulator, which generates 3.3 V.

The TLV62569 is a switching regulator with a maximum specified output current of up to 2 A. On this expansion board, however, the practical available current is limited by the common 78M05 regulator, which supplies both the 5 V load and the 3.3 V regulator. As a simple rule of thumb, the total load from the 78M05 should be kept around a maximum of 500 mA. Higher input voltage increases heat dissipation in the 78M05, which further limits the practical load.

The board has 3 mm mounting holes with a mounting spacing of 76.2 x 76.2 mm. The 25.4 mm and 33.02 mm pin spacing makes the board suitable for several types of ESP32 development boards.
