2.13-inch ink screen word card TF version + temperature and humidity + RTC

The hardware is modified from the 213 ink screen word card TF version of Mr. Xia Xiang’s project - low-cost replacement meow machine https://oshwhub.com/zhushengji/213-mo-shui-ping-dan-ci-ka-tf -ban-ben
v1.1 modification:
Added: SHT30 and AHT20 pads, specially designed heat island isolation, more accurate ambient temperature measurement, away from heat sources + double slots to isolate heat conduction (the main heat sources are ESP8266 and charging chips, which have been kept as far away as possible )
Added: RX8025T pad
modified: shoulder key moved from IO5 to RXD pin
Modified: fully compatible with Glycyrrhizic Acid Not Acid Boss version 2.44 hardware wiring https://oshwhub.com/jie326513988/tian-qi-mo- shui-ping-sd-ka-v2-42
added: CH340C added crystal oscillator bits but did not add capacitors (I have too many CH340Gs and I don’t want to buy CH340C).
Optimized: optimized a lot of unreasonable layout, wiring and paving. Ground, a relatively complete ground plane design for the bot layer √ No broken copper, no meaningless copper √, short-distance DCDC wiring for screen boost √, more headroom for the esp8266 antenna √
Maintains the casing compatibility of the original word card (to be tested )
 
You can make free samples. Note that the board thickness is 0.8mm. When placing an order, please note: (Process according to conventional processes! No half holes! Just open ordinary gongs.)
