maxim integrated 18 detailed description of hardware the max30001 ev system provides a single platform to evaluate the functionality and features of the max30001 with biopotential (ecg, r-to-r, and pace detection) and bioimpedance (bioz) measurement capabilities. the board contains jumpers and optional resistors and capacitors to test the max30001 under several conditions. a list of all jumpers and their respective functions is available in table 1 . an onboard 32.768khz crystal oscillator (u5) supplies fclk to the ic, but external frequency generation is supported. the ev system utilizes the max32630fthr cortex-m4f microcontroller for wearables for interfacing with the gui and optionally providing power to the max30001. the max32630fthr operates either from a host pc or directly from a li+ battery. if an sd card is present in the max32630fthr, register settings and measurement confgurations can be saved through the gui. when the ev kit operates without a host pc, pressing sw2 on the max32630fthr initiates the measurement and saves log fles to the sd card. logging is stoped by pressing sw2 a second time. refer to figure 17 for a simplifed schematic of the ev kit biopotential circuitry. table 1. description of jumpers jumper shunt position description j_ecgn 1-2* connects ecgn on the ic to c_ecgn on the ev kit. j_ecgp 1-2* connects ecgp on the ic to c_ecgp on the ev kit. en_bn 1-2 connects ecgn to bin. ep_bp 1-2 connects ecgp to bip. en_unbal 1-2* bypasses the ecg electrode unbalance on ecgn. ep_unbal 1-2* bypasses the ecg electrode unbalance on ecgp. ep_en 1-2 short ecgp to ecgn. j_bin 1-2* connects bin on the ic to c_bin on the ev kit. j_bip 1-2* connects bin on the ic to c_bin on the ev kit. rn 1-2* connects one end of r28 to bin. rp 1-2* connects one end of r28 to bip. dn_bn 1-2 connects drvn to bin. dp_bp 1-2 connects drvp to bip. bp_bn 1-2 short bip to bin. j_drvn 1-2 connects drvn on the ic to c_drvn on the ev kit. j_drvp 1-2 connects drvp on the ic to c_drvp on the ev kit. bb_sel 1-2* use vcm as the body bias. 2-3 use an adjustable voltage from 0v to ovdd as the body bias. adjust voltage with r7. j_rbias 1-2* connect an external 324k resistor to rbias. buff1_in 1-2 input to second buffer of u4. www.maximintegrated.com evaluates max30001 max30001 evaluation system

maxim integrated 21 powering the ev kit the max30001 ev kit can be powered from an external supply or directly from the max32630fthr. to use an external supply, install a shunt on jumper j_ext_pwr in the 1-2 position. this connects the ext_pwr test point to the boards 5v rail. set the power supplys output to +5v, disable the output, connect the positive lead to ext_ pwr and the negative to agnd1, then enable the supply. to power the ev kit with the max32630fthr, install a shunt on jumper j_sys in the 1-2 position to connect the sys node to the 5v rail. sys regulates the usb voltage or directly connects to the battery if present. the max30001 ic receives power from ovdd, avdd, and dvdd. these pins receive power either through the max32630fthr, externally through test points, or through adjustable ldos u2 and u3. to supply the ic from the max32630fthrs 1.8v and 3.3v rails, place a shunt in the 1-2 position on the 1v8 and 3v3 jumpers. to use the onboard ldos, place the shunts in the 2-3 position. two potentiometers are available to set the u2 and u3 voltages: r4 and r10. to operate the ev kit without a connection to a host pc or power supply, insert a microsd card into the max32630fthr. after saving a test confguration, disconnect the board from the host pc and connect a li+ battery to the max32630fthr. refer to the max32630fthr documentation for details on connecting a li+ battery. press sw2 to trigger the measurements saved to the sd card. the j_sys shunt must be in the 1-2 position for this confguration. confguring the board for measurement the max30001 ev kit offers several potential connection and component confgurations to enable a variety of tests. both the ecg channel and bioz channel allow for user- defned line resistance with resistors r26 and r27 for bioz, and r29 and r30 for ecg. by default, these resistors are populated with 0 shunts but can be changed to suit the application. the board also allows for the installation of external low-pass fltering capacitors on the ecg and bioz lines. capacitors c8 and c25 can create an external common mode flter for the ecg and bioz lines, respectively. c24, c29, c26, and c28 flter ecgp, ecgn, bip, and bin. the cutoff frequency of the flters is set by the value of these capacitors and the input resistors r26, r27, r29, and r30. the board also allows the ecgn and ecgp or bin and bip inputs to be shorted with jumpers ep_en and bp_bn, respectively. refer to the max30001 ev kit schematic and max30001 ev kit pcb layout sections for component connections and placements. ecg measurement the ev kit ships confgured to measure ecg with balanced electrodes, r-to-r, and bioz signals. the jumper confgurations required for these measurements are shown in figure 18 . connected jumpers are distinguished with solid black nodes in the jumper box. to use the electrode connectors on the ev kit, ensure the required shunts are installed. by default, the ev kit leaves the ecg channel balanced. by removing the shunts on en_unbal and ep_unbal, the ecgn and ecgp lines each include a 51k resistor and 47nf capacitor in parallel. www.maximintegrated.com evaluates max30001 max30001 evaluation system
maxim integrated 22 bioz measurement additionally, the ev kit includes a 100 resistor to verify the bioz confguration. attach shunts on rp and rn to connect the resistor to the bioz inputs and shunts on dp_bp and dn_bn to route the drive signal to the bioz channel. figure 19 illustrates these connections. refer to the max30001 data sheet for details on confguring a bioz measurement. note that the default setting of the current generator is fmstr/64 (about 500hz) and the bioz channel has an internal high-pass flter with a default 1khz cutoff frequency. in order to correctly measure the 100 resistor, bypass or lower the flter cutoff frequency or increase the current generator frequency. pace detection to enable pace detection, the ecgn and ecgp lines must be connected to bin and bip by shunting en_bn and ep_bp, then confguring the device registers as described in the ic datasheet. refer to figure 20 for a jumper confguration to measure ecg with pace detection. alternatively, ep_bp and en_bn can be left open and j_bip and j_bin shunted. this measures pace directly on the bip and bin inputs and allows another signal to be measured on the ecg channel. in this confguration, the measured pace signal may not correspond to the ecg measurement. figure 18. default measurement channel jumper configurations ep_en 0 bp_bn 0 en_unbal ep_unbal rp rn ep_bp en_bn j_ecgp j_drvp j_ecgn j_bip j_bin j_drvn 47nf 47nf drvn drvp bin bip ecgn ecgp drvn drvp bin bip ecgn ecgp 100 dp_bp dn_bn 0 0 www.maximintegrated.com evaluates max30001 max30001 evaluation system
