Hi forum! I'm building a device with 8 OLED-displays and for this reason I need 8 SSD1306 objects (Adafruit library) in RAM. Arduino Mega with 8KB SRAM is fine, but UNO is just not enough to manage the load.
However, the Mega is larger in height than my entire device. Also, I only need 6 pins (SDA, SCL and 4 digital inputs), so the Mega is clearly overkill.
Are there any small boards (genuinos or clones or whatever) that are compatible with the Arduino library ecosystem and have at least 8KB SRAM? By small I mean that the height is at most 45mm.
Thanks in advance!
