  We present non- and ultra-relativistic Jackiw-Teitelboim (JT) supergravity as
metric BF theories based on the extended Newton-Hooke and extended AdS Carroll
superalgebras in two spacetime dimensions, respectively. The extended
Newton-Hooke structure, and, in particular, the invariant metric necessary for
the BF construction of non-relativistic JT supergravity, is obtained by
performing an expansion of the $\mathcal{N}=2$ AdS$_2$ superalgebra.
Subsequently, we introduce the extended AdS$_2$ Carroll superalgebra, and the
associated invariant metric, as a suitable redefinition of the extended
Newton-Hooke superalgebra. The mapping involved can be seen as the
supersymmetric extension of the duality existing at the purely bosonic level
between the extended Newton-Hooke algebra with (positive) negative cosmological
constant and the extended (A)dS Carroll algebra in two dimensions. Finally, we
provide the Carrollian JT supergravity action in the BF formalism. Moreover, we
show that both the non-relativistic and the ultra-relativistic theories
presented can also be obtained by direct expansion of $\mathcal{N}=2$ JT
supergravity.
