Spare dies: 224 in Swarm, 96 in Kris’s office (untested, dated 2018/07/11)
9 Q boards + 8 QX boards + 15 dev boards
Ahad tested 20 chips (results: https://tinyurl.com/finchworm):
Chip | Status | Owner |
|---|---|---|
1 | Works perfectly (VDDD_LDO_OUTPUT increases to ~1.1V) | Fil (on SARA board) |
2 | Not programmable | Ahad |
3 | Works perfectly (VDDD_LDO_OUTPUT increases to ~1.1V) | Ahad |
4 | Not programmable | Ahad |
5 | Not programmable | Ahad |
6 | Programmable, draws VDDD_LDO_OUTPUT to ~1.3V and draws >1 mA of current even without the radio turned on | Ahad |
7 | Not programmable | Ahad |
8 | Works perfectly (VDDD_LDO_OUTPUT increases to ~1.1V) | Ahad |
9 | Programmable, draws VDDD_LDO_OUTPUT to ~1.3V and draws >1 mA of current even without the radio turned on | Alex (on SARA board) |
10 | Programmable, draws VDDD_LDO_OUTPUT to ~1.3V and draws >1 mA of current even without the radio turned on | Ahad |
11 | Not programmable | Ahad |

19 | Programmable, draws VDDD_LDO_OUTPUT to ~1.3V and draws >1 mA of current even without the radio turned on | Ahad |
20 | Not programmable | Ahad |
21 (1b) | Programmable, draws VDDD_LDO_OUTPUT to ~1.3V and draws >1 mA of current even without the radio turned on | Fil (on SARA board) |
Ahad also used the NI Current DAQ to generate time-series current data for chips 21-40, found here: https://drive.google.com/open?id=1tEYlE4YMUUR62iSXECxSKdOlVVgLKy8X

2 additional chips on SARA boards:
1 functional
1 that works with VDD jumper workaround

R4 | Alex board 2. Boots with VDDD=1V connected during programming (double boots when we kept VDDD connected). Once booted with VDDD connected and clocks calibrated, then we can remove VDDD and boot repeatedly. | Austin/Alex |
R5 | Did not boot with VDDD=1V but perhaps we could try different voltages in the future | Austin/Alex |
R7 |
2. Boots with VDDD=1V connected during programming (double boots when we kept VDDD connected). Once booted with VDDD connected and clocks calibrated, then we can remove VDDD and boot repeatedly. After removing VDDD. VDDD_LDO output=0.962V | Austin/Alex |
R13 | didn’t work after 5 attempts | Austin/Alex |
R14 | didn’t work | Austin/Alex |
R15 | Austin/Alex | |
Q2 | Austin/Alex | |
14 (yellow wire on it) | Austin/Alex | |
Q6 | Cold boot working radio! | Austin/Alex |
