Hi all, I just got given a handful of these things
https://www.amazon.co.uk/dp/B07VL6G914?ref=ppx_yo2ov_dt_b_fed_asin_title
I found the pinout 'diagram', this one here
Looking at the available pins, I believe this can support (simultaneously) up to 11 simple devices(LED, switch input, trigger output)
I would like something that allows me to connect
3 (maybe 4?) LED's
2 button / hall effect / other inputs
4 outputs to relays or transistors
I can see it supports I2C but would the use of that consume a Pin used for the others?
Would this fit the bill?
Cheers

If you are not connecting an i2c device, pins 2 and 3 are available as digital pins.
Pin 3 has PWM capabilities, as do 9, 10, and 11.

Microcontroller: ATmega32U4
Clock Speed: 16 MHz
Operating Voltage: 5V DC
Digital I/O Pins: 10
PWM Channels: 4
Analog Input Channels: 5
UART: 1
I2C: 1
Micro USB: 1
Flash Memory: 32 KB of which 4KB used by bootloader
SRAM: 2.5 KB
EEPROM: 1 KB
Thanks for the feedback. I will have a play with them, there are a couple of Nano's that they would potentially replace

For reduced size, have a look at this...
