It has a fine resin surface and sturdy back suitable for outdoor environments. A 2mm JST connecter is attached to the penal, which makes it perfect to team up with most of our can-use-solar-power-supply boards.
The typical open circuit voltage is around 5V, depending on light intensity. To prevent any damage to boards that accept a narrow range of input voltage, like Lipo Rider, it’s recommended to check whether the OC voltage is safe before any connection.
