FM Radio Kit - DIY V2.0 - Kitronik 2157

A set of elements allowing you to build your own radio. The module is based on two circuits, the latest generation Si4820 radio receiver,whichoffers high qualityreception and easy tuning, and a single-channelNCP2890D amplifier, allowing you to connect a speaker of up to 1 W. The set requires the solder to be soldered to a plate. The board dimensions are 88 x 46 mm. The unit can be poweredfrom 2.5 C to 5.5 Vor 3AA batteries.

Additional materialsThe manufacturer provides teaching notes and a sheet with important information for the users of the kit.

The kit requires THT elements to be soldered in.

The manufacturer has prepared aninformationnote which includes a description of the radio's operation and short assembly instructions. The kit contains elements that require soldering.
