1. Power input terminal, with the upper end being the ground wire and the lower end being+5V.
2. LT3461 power chip with high ripple noise suppression ratio.
3. Power indicator light.
4. LP2985, LDO can effectively filter out low-frequency noise and generate a very pure+5V, providing power for ASD1256.
ADR431BRZ, B series is a high-precision benchmark. Reference chip, generating a high-precision 2.500000 V reference
6. Benchmark test holes.
7. Simulated input terminal, there are a total of eight input ports in AIN0-AIN7, which can be used as 8 independent single ended inputs or as 4 sets of differential inputs. AIN0 and AIN1 are grouped together, and AIN2 and AIN3, AIN4 and AIN5, AIN6 and AIN7 are grouped together
