@thzinc pretty near, but it's not a data logger!
The mcu is an #esp8266 (a D1 Mini clone), as you said it's connected via i2c to a #PN532 -based #NFC reader. The module to the right is not only an sdcard slot support. Is a " #DFPlayer ", a sketchy module containing an #MP3 player and amplifier, controllable via #UART. Pretty limited, but I needed someting cheap, quick and dirty, and it ticks all the boxes.
The idea is building an electronic storyteller (something like https://www.myfaba.it/ or https://lunii.com/ , but without the whole closed source stack, tracking and remote bricking they bring along) for my daughter. -

Как стартапу создать свой первый прототип с бюджетом 25к рублей?
Показываем прототип, который разрабатывали с нуля, не имея за спиной какого-то огромного опыта или доступа к чужим разработкам. Четыре месяца мы упорно трудились ради того, чтобы все наши статьи и материалы были не пустым звуком, а показывали перспективу нашего опыта, а также продвигали продукт к выходу на рынок. Рассмотрим как успехи, так и неудачи с сложностями. Как команда развивалась за это время, и какие технические решения были выбраны. Узнать о прототипе

Someone commented on one of my projects that the NXP PN532 is getting old, and there are newer chips. I found a later NXP one, but not sure it does what I want.
I like the HSU mode, as it allows it to run on a short run of wires that are properly driven (rather than the pull ups of I2C).
I like the GPIO as I use these for status LEDs on the reader.
Anyone know of a newer NFC chip that does HSU and has a few GPIO?
