@Links2004
yes
d-anders
@d-anders
good
Markus
@Links2004
the LDO converts the 5V to 3.3V
d-anders
@d-anders
i have a few bare esp-01 and esp-12, but the bare esp-12 isn't optimal for quick tests
yeah
i think my notebook is capable of delivering 500ma to the usb so it should be fine i guess
Markus
@Links2004
yes the ESP runs stable at 250mA
d-anders
@d-anders
the boards look pretty
Markus
@Links2004
for test i mostly use whats called esp8266 testboard
http://4.bp.blogspot.com/-ltG_dy6GNvA/VLo4yAyfpUI/AAAAAAAAAMU/sb1VWUuM9z8/s1600/testboard-layout.jpg
have a LED at eache pin which is really usefull
d-anders
@d-anders
the one that comes with battery-box?
Markus
@Links2004
yes
d-anders
@d-anders
yeah, also has everything needed
Markus
@Links2004
but with the LEDs its not really low power :)
d-anders
@d-anders
doesnt really matter when testing though
is it 4MB?
Markus
@Links2004
it has a ESP12 most of them has 4MB
d-anders
@d-anders
$3.8 vs $5.1 for nodemcu
tough call
Markus
@Links2004
but no USB on them, can be good and not at the same time.
d-anders
@d-anders
yeah, i have a few usb->ttl
only downside is having to use a seperate power adapter
more cables when testing
Markus
@Links2004
you can connect 5V to it :)
d-anders
@d-anders
right, from the usb-->ttl adapter, didnt think of that
Markus
@Links2004
at the same port where the batterys are connected it has a LDO
d-anders
@d-anders
yeah i guessed that since it looks like it has 3 batteries
i usually power my esps from a 230v-->3v adapter btw, it works great
Markus
@Links2004
looks really usful for the ESP01
d-anders
@d-anders
yeah, but why on earth didnt they go for an usb interface
Markus
@Links2004
but it costs more then a complete ESP01
Harrison Mclean
@h4rm0n1c
they always use the bloody cts pin sigh
d-anders
@d-anders
it looks like the idea is to use it for easy programming of esp-01
connect-> program->remove
Markus
@Links2004
then you can use some duketape and jumerwires and a FTDI@3V3 ;)
d-anders
@d-anders
well true
but not if you would want to transfer the same prog to hundreds of them
Markus
@Links2004
why not when the duketape holds the wires together its the same as the board, and you dont need to press the button.

@Links2004 i use currently this reset logic.
Markus
@Links2004
yes?
onkelfunny
@onkelfunny
I have to reckon with problems?
everything works without the RTS signal.. i have to press the flash button and the reset button to flash the module
Markus
@Links2004
you complete disable the automatic with removing the RTS
d-anders
@d-anders
bought the pretty nodemcu
Markus
@Links2004
if DTR connected or not make no difference if RTS is not connected too
onkelfunny
@onkelfunny
in this case its easier to connect the wires direct to the buttons, correct?

you can also try it like this:
