What if there was an Arduino that could do everything?...

I aimed to make the "Ultimate Ardiuno", the Arduino Bannou (万能 meaning "Eveything/multitool/all-purpose"). This board has the complexity of a high end development/research board while being able to be easily coded. This board aims to be an Everyday-carry PCB that can be used for whatever you need. The following features are implemented on this board:

Features:
USB port x2 [Program, Bat Charge] - USB-C-SMD-DIP_TYPEC
IR, UV, Ambient light sensor [I2C] - TSL25911FN 
Analog light sensor [Analog] - GT36528
Precision temp sensor [I2C] - NCT75MNR2G
IR Proximity sensor [I2C] - VCNL4040M3OE
9 Axis IMU [I2C] - BNO055 -------------- {NOT CONFIRMED IF WORKING PROPERLY}
Precision 3 axis compass [I2C] - MMC5983MA
Digital potentiometer x2 [I2C] - TPL0102-100RUCR
Analog potentiometer x2 [Analog] - VGF39NCHXT-B204
Individually addressible LEDs x25 [Digital] - XL-2020RGBC-2812B (aka WS2812B) 
16 bit ADC - [I2C] - ADS1115IRUGR
5V buck converter [Power] - MPM3610AGQV-Z
3V3 buck converter [Power] - MPM3610AGQV-Z
3V3 LDO [Power] - ADM7170ACPZ-3.3-R7

Side-mounted button x3 [Digital] - TSA002A3526B
Crowbar diode x3 [Power] - 1N4148WS-7-F
ESD Protection x3 [Power] - SMF05CT1G
Power Switch [Power] - SW-TH_MSK12C02
PTC Resettable fuse [Power] - SMD1206-100C-16V
Barometric pressure sensor [I2C] - ICP-20100
I2C Multiplexer [I2C] - TCA9548APWR
Logic level shifters [Digital] - BSS138W-7-F
Passive buzzer [Digital] - MLT-8530
Rail to rail 12 bit DAC x2 - [I2C] - MCP4725A0T-E/CH
Microphone [Analog] - ICS-40180
Microsd card reader [ICSP] - TFP09-2-12B
Current sensor x2 - ACS712ELCTR-05B-T
battery charging system - TP4056 DW01A, & FS8205A

+ plenty of power and ground connections
+ broken out USB differential pair
+ All unused GPIO ports broken up that arent used by Arduino (PJ2-PJ7)
+ multiple I2C channels broken out, from multiplexer, LL shifted I2C (3v3)
+ EMC practices followed as well as reasonably achievable
