Description:

• Dedicated expansion board for ESP32-C3 SuperMini
• Designed to compensate for limitations of the original ESP32-C3 SuperMini board
• Supports 3.7 V lithium battery via PH2.0 connector
• Supports lithium battery charging over USB
• Charging: green LED ON
• Fully charged: green LED OFF
• All IO pins broken out for easy sensor connection
• Two power rails: VCC1 and VCC2
• Default output voltage: 3.3 V on both rails
• PCB solder jumper allows switching output to 3.7 V (battery voltage)
• Factory default: 0 Ω resistor ties rails to 3.3 V
• For 3.7 V: remove 0 Ω resistor and short the three pads with solder
• VCC1 and VCC2 can be used independently; only one rail needs to be used as required
