my own dev board
Im looking to making my own dev board but am conflicted on.which microcontroller to go for. The attiny88 is pretty decent in all fields especially cost, but is rather underpowered. The esp 12f and variants has iot stuff and is cheap but has very few usable pins. And the atmega the arduino nano uses is a bit pricey and possibly trickier, but is essentially very good performance wise. What do I do?

Thank you for the advice :)))
I ordered some cheap microcontrollers to try with first

I ordered the esp 12 F cuz it seemed rather simple to start with, but they do hav a rather lackluster pinset
I heard theres a lil component that can essentially act as a pin multiplier

I shouls probs start stimple
Handful of resistors
Voltage regulator
And uhhh
Usb converter
So I can actually program the thing
Anything im missing?

How I made Own ESP32 Development board
A small, fully featured and cheap wifi module with circuit and PCB designs. let's play with 32 bit microcontrollers. By Electro BOY.
@v0id i ordered 10 esp 12f and 1 esp 32 wroom
Twas oddly cheap
Total was like 20 bucks
My current step plan is
1) make a components list for a base board
2) order the components
3) design the board in probs that EDA ware
4) design the pcb itself
5) get the pcb made and shipped
6) solder
7) test
8) then try making a more custom one, with new peripherals. Here you repeat step 1 till 7 but for the new board
My current ideas are:
-a board thats good for designing model rocketry, built in accelerometer, sd card slot, altimeter, and a bunch of pins for things like servos
-a board thats got a built in pwr supply, more gimmicky then the latter but might help eliminate things like bulky power supplies that are unnesisarily large
-a board with a built in mini lcd, alrdy exists but might be cool to give it a shot
-a board with a built in solar cell, and a very small lcd to show battery charge.
Theres a lot of oppurtunity for cool peripherals
