Re: Small ESP32 Modul ( all include in new ESP32-PICO )

That looks like the same arrangement of pins as in D2WD, is it not? ESP32-D2WD’s pins GPIO16,GPIO17,SD_CMD,SD_CLK,SD_DATA_0 and SD_DATA_1 are used for connecting the embedded flash, and are not recommended for other uses. You could be right. And pSRAM pins are "TBD" the confuse is, using ...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

There is a complete re-assignment of the SIG PINS? whats_happend_here.png Current PIN assignment: IO16 and IO17 was CS and CLK for pSRAM and also SD_CMD was a /CS _.jpg very confusing Who can ever think of something? but let see what comes in next time on desktop and revise on documents - to early t...

Re: What would you like to see in The Next Chip?

cause espressif celebrate 10th anniversary in 2018, i think we can push some gags in a limited 10 Year special "stamp" package, perhabs as "SIP package" - No black package but a clear (transparent) package (want to see what is in it like the neopixel with bonds and so on ) - an e...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

Oh .. info taken from the datasheet i do not believe this but i have to ask before i think detailed : ESP32 SIP-D4 VDD_SDIO_NC.png looks like there is no support for 1.8V pSRAM ? is there a 3.3V Flash in the SIP ? so we can use 3.3V pSRAM then over regular 3.3V power supply ? so i can think we get a...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

Small ? ;p Ok .. how you think over this ESP32-PICO breadboard modul ;-) the most taken space is from USB, LDO and button parts. the complet ESP32 SoC and crystal and flash and so on is in the PICO package. :) ( i like this - cause there are 2 rows free on a standard breadboard on each side now) i ...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

Do you go to MP? Or where we can catch your nice Board ( like it ) if you can use in your next PCB that is 30% smaller you can save again place cause you did not need OSC and Flash example. On the shelves in Q4 2018 :D ok - i will wait Going smalled will not help us, because we still need to includ...

I wanted not make advertising for MT so I have the module cut off in the picture but if you already recognize it ;-) i can answere free: the SIG of MT7688 DUO and MT7688 modul is ok with this chip antenna. btw same with MT7628 and MT7621 i like it fo...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

He is already using d2wd and tiny crystal and passives but PICO may save a few mm. NFC section looks biggest. Maybe "ESP-2018" will have built in NFC like rtl8711 you're right, i would use a small chip antenna in the meantime ( pic is for a size compare with an ESP32-D2WD - it's the right...

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

Small ? ;p Here my version ESP + LED DRIVER + 1.8v + 3.3v, plus I2C 1.8v->3.3v->1.8v plus battery managment. + RFID + RG Leds + FTDI + wifi antenna + Pedometer Next version will be 30 % smaller. Very nice! Well done! Do you go to MP? Or where we can catch your nice Board ( like it ) Not sure you ha...
