This is an arduino nano based soldering station. **Tested, working version.**
-Designed to work with rotary encoders.
-Built in Beeper.
-Built in memory buttons to store often used temperature values.
-Built in Debounceing for the buttons. (up to 7 buttons, built in 3 buttons)
-Designed to work with a MAX6675 module for temperature readings from a K-type thermocouple.
-Built in LCD head...
So far I have not found an ESP development module which can be inserted to a socket sideways e.g. to save PCB footprint (for use in smaller enclosures) and to increase module density (e.g. in a HPC application / ESP cluster / multi-ESP configurations).
Here is one design I created (feel free to use/modify/improve/etc).
I wish that some day a manufacturer realizes its potential and creates a produc...
I got sick of wiring up ESP-12 on the simple breakout boards to external devices where you needed extra VCC and GND connections. The nodeMcu version have the built in serial and regulator that are not much good for low power.
So this is my alternative, focused around I2C and mainline I/O with VCC and GND close by, as well as options for configuring the reset pin, for wake up and external
The AT24C256C provides 262,144 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 32,768 words of 8 bits each. The device’s cascadable feature allows up to eight devices to share a common two-wire bus.
