About This Product

A small CPU board equipped with Renesas HD64F2238B 12.288MHz. Built-in Flash 256KB, external SRAM 128KB, rich built-in peripherals, 5V single operation. DIO, insulation, and universal boards sold separately can be expanded. This is a continuing product from Yellow Soft, and the old model number is YH2238. H8S/2238 is a product with a built-in subclock (32kHz oscillation circuit).

■Note]

This board is the same product that was developed and sold by the former Yellow Soft Co., Ltd., which went out of business, as a prototype and for learning purposes, and which our company continues to produce. This is a product that originally did not have environment-related parameters such as RoHS, and we are unable to provide it, so please be aware of this before considering it.
