It can be found on e.g. the Renesas YRSK-LCD-PMOD extension board, which comes with various Renesas development kits (e.g. Renesas Starter Kit+ for RZ/A1H[1]). ST7715R and ST7735R are very similar. Their major difference is that the former is restricted to displays of up to 132x132 pixels, while the latter supports displays up to 132x162 pixels.
