ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier feather Level shifting circuitry so you

Level shifting circuitry so you can run it with 2

we managed to squeeze 12-bit color (4096 colors) with 20% CPU usage but this display would really shine if driven by any FPGA

There are 30 RGB LEDs per meter

we set it up so words flow from one matrix to the other - kind of like a sign in front of a miniature car dealership

ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier feather Level shifting circuitry so youFor microcontrollers without an analog to digital converter or when you want a higher precision ADC, the ADS1115 provides 16 bit precision at 860 samples second over I2C. The chip can be configured as 4 single ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single differential signals to the full range. We like this ADC because it can run from 2V
